If your refrigerator runs constantly — the motor never seems to stop, the hum never fades — something is off. A healthy fridge cycles on and off throughout the day. When it runs non-stop, it’s working overtime to maintain temperature, and that extra effort is costing you money on your electricity bill while quietly wearing out the compressor.
For Ottawa homeowners, a fridge that runs constantly is one of the most common appliance complaints we hear at Yanfix. Sometimes the fix is surprisingly simple — a dirty condenser coil, a worn door seal, or a thermostat set too low. Other times, the problem points to a failing component that needs professional attention before it becomes a full breakdown.
In this guide, we’ll walk you through every major reason your refrigerator runs constantly, explain what the clicking and buzzing noises mean, cover what to do when the door won’t close properly, and help you decide when a DIY fix is enough versus when it’s time to call local refrigerator repair technicians. Let’s get to the bottom of it.

Why Does a Refrigerator Run Constantly? The 6 Most Common Causes
A refrigerator runs constantly when it cannot maintain the set temperature efficiently. That inefficiency can come from several directions — some external, some mechanical. Here are the six causes our Ottawa technicians encounter most often.
1. Dirty or Clogged Condenser Coils
The condenser coils release heat from the refrigerant into the surrounding air. When they’re coated in dust, pet hair, and kitchen grease — which happens gradually over months — they lose their ability to dissipate heat efficiently. The fridge compensates by running longer and longer cycles.
This is the single most common reason a refrigerator runs constantly, and it’s entirely preventable. Condenser coils are typically located on the back of older fridges or beneath the unit on newer models, behind a removable grille.
Studies from appliance manufacturers suggest that dirty condenser coils can reduce refrigerator efficiency by up to 30% — meaning your fridge works nearly a third harder than it should, shortening the compressor’s life in the process.
2. Worn or Damaged Door Gasket
The door gasket — the magnetic rubber seal around the perimeter of the fridge and freezer doors — is your refrigerator’s first line of defence against warm air. When it cracks, hardens with age, or pulls away from the door frame, warm air constantly seeps into the cabinet. The fridge detects the temperature rise and keeps the compressor running to compensate.
A door won’t close properly if the gasket is deformed or if the door itself is misaligned. You can test your gasket with a simple dollar bill: close the door on a piece of paper and try to pull it out. If it slides out easily with no resistance, the seal is failing and needs replacement.
3. Incorrect Temperature Settings
It sounds almost too obvious, but an incorrectly set thermostat is a frequent culprit. If someone has nudged the temperature dial to its coldest setting, or if the fridge was bumped during cleaning, the appliance may be working hard to hit a target temperature that’s far below what’s necessary.
The recommended settings for a healthy refrigerator are 2–4°C for the fridge compartment and -18°C for the freezer. Anything colder than this pushes the compressor to run constantly without delivering meaningful additional food preservation.
4. Refrigerator Placed in a Hot Location or Overcrowded
Your refrigerator’s environment directly affects how hard it has to work. A fridge placed next to the stove, in direct sunlight, or in a poorly ventilated space will run constantly because the ambient heat continuously warms the cabinet. Similarly, leaving the doors open frequently or placing large amounts of warm food inside at once forces prolonged running cycles.
Overpacking the fridge can also block internal air circulation, creating warm pockets that the thermostat registers as a temperature failure — triggering longer run times.
5. Frost Buildup in the Freezer Compartment
On frost-free refrigerators, a defrost heater, thermostat, and timer work together to melt ice buildup automatically. When any part of this defrost system fails, frost accumulates on the evaporator coils — the coils responsible for actually cooling the air inside the fridge. Frost-covered coils can’t exchange heat properly, so the compressor runs constantly trying to compensate.
Signs of a defrost system failure include visible ice buildup on the back interior wall of the freezer, the freezer working fine but the fridge section not staying cold, and the compressor running continuously.
6. Failing Compressor or Start Relay
The compressor is the heart of your refrigerator — it pumps refrigerant through the cooling circuit. The start relay is a small component that helps the compressor start each cycle. When the start relay is failing, the compressor may attempt to start repeatedly but struggle to complete its cycle, causing the unit to run constantly and often producing a clicking sound in the process.
A clicking sound coming from the back or bottom of your fridge every few minutes is a classic sign of a failing start relay. This is one of the cheaper compressor-related repairs and worth addressing quickly before the compressor itself fails.

What Those Clicking and Buzzing Noises Actually Mean
A refrigerator that runs constantly and makes clicking or buzzing noises is telling you something specific. Don’t ignore these sounds — they’re diagnostic clues.
Sound | Where It Comes From | What It Likely Means |
Clicking every few minutes | Back or bottom of fridge | Failing start relay — repair soon |
Loud buzzing or humming | Back of fridge | Condenser fan or compressor strain |
Buzzing when ice maker fills | Inside freezer | Normal — ice maker valve opening |
Rattling or vibrating | Under or behind fridge | Drain pan loose or item on top of fridge |
High-pitched squealing | Inside freezer | Evaporator fan motor bearing failing |
Gurgling or hissing | Inside walls | Normal — refrigerant flowing through coils |
The most important distinction: normal refrigerator sounds are low, steady, and periodic. Clicking noises that repeat every few minutes, loud buzzing that doesn’t stop, or sudden new sounds after years of quiet operation are all signs worth investigating. When in doubt, call local refrigerator repair technicians who can identify the source quickly.
The Impact of a Door That Won’t Close Properly
A door that won’t close properly is more than a minor inconvenience — it’s one of the most energy-intensive problems a refrigerator can have. Every millimetre of gap in the door seal is a continuous invitation for warm, humid air to enter the cabinet.
In Ottawa’s climate, where summer humidity can be high and winters mean a warm kitchen versus cold entryway air, a leaking door seal forces your fridge to work dramatically harder. Homeowners often see a noticeable uptick in electricity costs before they even notice the fridge is running constantly.
There are three common reasons a refrigerator door won’t close properly:
- Worn or deformed door gasket: The rubber seal loses its magnetic grip and flexibility over time. A gasket that was once perfectly flush can develop gaps, especially at the corners.
- Misaligned door hinges: Hinges can loosen or bend over time, particularly on heavy French door and side-by-side models. A misaligned door simply won’t meet the frame squarely.
- Overpacked shelves or door bins: If items stored in the door are too tall or protruding, they physically prevent the door from sealing fully. This is the easiest fix — rearrange your storage.
Replacing a door gasket is a manageable DIY repair on most fridge models — replacement gaskets are available for major brands and typically snap or screw into the door groove. However, hinge realignment often requires removing the door entirely and can be tricky without experience. If in doubt, a trained technician from Yanfix can handle it quickly, usually within a single same-day visit.
How to Troubleshoot a Refrigerator That Runs Constantly
Before reaching for the phone, work through this checklist. Several common causes can be resolved at home in under 30 minutes.
- Check and adjust the temperature settings. Ensure the fridge is set to 2–4°C and the freezer to -18°C. Avoid the coldest setting unless your kitchen runs very warm.
- Inspect the door gasket. Run your hand along the door seal with the door closed to feel for cold air escaping. Do the dollar bill test on all four sides of both doors.
- Clean the condenser coils. Unplug the fridge, remove the back grille or bottom kick plate, and vacuum the coils with a brush attachment. Dust buildup of even a centimetre can cause significant inefficiency.
- Check the door hinges. Open and close the doors — they should feel firm and level. If a door drops or shifts, the hinge may need tightening or replacement.
- Look for excessive frost in the freezer. If you see a thick layer of ice on the back wall of the freezer, the defrost system may be failing. Manually defrosting the unit (unplugging for 24–48 hours with towels placed inside) is a temporary fix, but the underlying defrost component will need replacement.
- Ensure adequate clearance. The fridge needs at least 5 cm of clearance on the sides and back for proper ventilation. Pull it away from the wall if needed.
- Listen for clicking from the back. A repeated clicking sound every few minutes when the compressor tries to start signals a failing start relay. This small part is inexpensive to replace but needs to be done promptly.
If you’ve worked through these steps and your fridge still runs constantly, or if you’re hearing persistent clicking or buzzing noises, it’s time to bring in a professional.

Repair or Replace? How to Make the Right Call
When a refrigerator runs constantly and the diagnosis points to a major component, homeowners often ask the same question: is it worth repairing, or should I replace it? Here’s a practical framework.
Component | Repair Makes Sense | Consider Replacing If… |
Start relay | Almost always — inexpensive part | Compressor is also failing |
Door gasket | Always — low cost, high impact | Door frame itself is warped |
Defrost thermostat / heater | Yes, if fridge is under 10 years | Multiple defrost parts failing together |
Condenser fan motor | Yes, on units under 10 years old | Unit is over 12 years old |
Compressor | Only on newer, high-value units | Repair exceeds 50% of replacement cost |
Evaporator fan motor | Yes — straightforward repair | Multiple components failing at once |
The 50% rule is a reliable guide: if the repair cost is more than half the cost of a comparable replacement fridge, replacement is usually the smarter long-term investment. A Yanfix technician will always give you an honest assessment — we won’t recommend a repair that doesn’t make financial sense for you.
Maintenance Tips to Prevent Your Fridge From Running Constantly
Preventive maintenance is the most cost-effective refrigerator strategy there is. These habits take minimal time but can extend your appliance’s lifespan by years and keep energy bills in check.
Task | Frequency | Why It Matters |
Clean condenser coils | Every 6–12 months | Prevents constant running from heat buildup |
Inspect door gaskets | Every 3–6 months | Catches seal failure before energy costs spike |
Check temperature settings | Seasonally | Prevents over-cooling in winter, under-cooling in summer |
Clean interior drain hole | Every 3 months | Prevents water pooling and odours |
Ensure proper clearance (5+ cm) | When repositioning | Allows heat to escape from condenser coils |
Level the refrigerator | Annually | Ensures doors seal properly and close under gravity |
Defrost manual-defrost models | When ice exceeds 1 cm | Prevents evaporator coil efficiency loss |
One often-overlooked tip: make sure the refrigerator is level, or very slightly tilted back. This allows the doors to swing shut on their own under gravity — preventing the accidental half-open door that silently drains your fridge’s efficiency all day.

FAQ: Refrigerator Running Constantly in Ottawa
Q: Is it normal for a refrigerator to run constantly?
A: No — a healthy refrigerator cycles on and off throughout the day, typically running 40–80% of the time. If your fridge runs constantly without stopping, it’s working harder than it should. The most common causes are dirty condenser coils, a failing door gasket, or a defrost system problem. All are worth addressing promptly to protect the compressor.
Q: Why is my refrigerator making a clicking noise every few minutes?
A: A clicking noise that repeats every few minutes — especially from the back or bottom of the fridge — usually indicates a failing start relay. This small component helps the compressor start each cooling cycle. When it fails, the compressor tries and fails to start, causing the clicking sound. The start relay is an inexpensive part, but it should be replaced quickly before the compressor sustains damage.
Q: Why does my refrigerator make a buzzing noise?
A: A buzzing noise from the back of the fridge often indicates the condenser fan or compressor is working under strain — usually due to dirty coils or a component starting to fail. A buzzing sound from inside the freezer when the ice maker fills is normal. If the buzzing is loud, new, or constant, call local refrigerator repair technicians to diagnose it before it escalates.
Q: My refrigerator door won’t close properly — can I fix it myself?
A: It depends on the cause. If items in the door are blocking it, rearrange your storage. If the gasket is worn or has pulled away from the door, a replacement gasket is available for most major brands and can be installed as a DIY repair. If the hinges are misaligned, the door may need to be removed and re-hung — a task best handled by an experienced technician to avoid damaging the door or frame.
Q: How much does refrigerator repair cost in Ottawa?
A: Most common fridge repairs in Ottawa range from $100 to $350, depending on the part required and the complexity of the repair. Start relay replacements and gasket replacements sit at the lower end; compressor work and sealed system repairs are on the higher end. At Yanfix, we provide upfront pricing so you always know the repair cost before committing.
Q: How do I find reliable fridge repair in Ottawa near me?
