The Most Common Causes
These are the failure modes our technicians see most often on this symptom — listed in rough order of frequency. We don't publish step-by-step repair instructions for liability reasons, but the diagnostic process below identifies which one applies to your machine before any parts get swapped.
🔁 Older fridge stopped cooling and clicking
An older fridge that quits cooling and clicks every few minutes is almost always the compressor start relay / overload failing to start the compressor — usually NOT a dead compressor. It's a cheap, fast part that often brings the fridge right back to life. We test it before condemning anything.
Frosted-over evaporator coils
When the defrost system fails, frost builds on the coils until air can't circulate. The freezer stays cold (right next to the coils) but the fridge section warms. Most common cause.
Failed evaporator fan or condenser fan
Without airflow, cold doesn't move where it needs to go. You may hear the fan trying to spin against ice, or hear silence where you should hear airflow.
Stuck or broken damper between compartments
Some models use a motorized damper to control cold flow into the fresh food side. When it fails closed, the fridge warms while the freezer stays cold.
Dirty condenser coils
Years of dust and pet hair on the back/bottom coils reduce heat exchange. The compressor runs constantly but can't keep up. Free or cheap fix — and missed surprisingly often.
Sealed system failure (compressor, refrigerant leak)
The big one. Compressor failure or refrigerant leak. The cost conversation changes here — this is where 'should I replace it' becomes a real question.
Before You Call — What's Safe to Try
Some of this you can absolutely handle, and we'll tell you straight which parts. Other fixes are doable but carry real risk, and a few you should never touch. This is general guidance, not professional advice — always unplug the appliance (or shut off the gas/water) before you check anything, and if it feels beyond you, that's exactly what the $50 Quick Check is for.
✅ Safe to try yourself
- Vacuum the condenser coils. Dust-packed coils are the most common cooling killer. Find them behind the kickplate or on the back, and vacuum them clean. Give it 24 hours to recover.
- Check the settings and mode. Confirm the temp dial was not bumped, and that the unit is not in demo/showroom mode (check the manual for the exit combo).
- Clear the vents. Food packed against the interior air vents blocks cold air. Leave space around them.
- Check the door seals. A door not sealing lets warm air in. Do the dollar-bill test around the gasket.
⚠️ Doable — but know the risk
- Condenser or evaporator fan motor. A dead fan stops cold air moving — replaceable, but it means accessing the back panel or freezer wall.
🛑 Call a pro — don't touch this
- THE SEALED SYSTEM — compressor, refrigerant, leaks. This is a hard stop: it requires EPA certification and special equipment, and is illegal to open without it.
- Control board
The Honest Answer
Frost, fan, damper, and coil issues — yes every time, $200–$450 range. Sealed system repairs (compressor, refrigerant) start at $200 and climb depending on the system and parts. On older units (10+ years) some sealed system failures are still the call where replacement may win — we give you both numbers honestly, no pressure either way. Parts availability and labor complexity matter more than the age of the machine. A well-built ten-year-old appliance with an available part is often worth fixing twice. A newer unit with a discontinued board is the harder call. Our techs lay both options out side-by-side — repair cost vs. replacement cost — and let you decide. Try the replacement calculator for a quick framing, but every situation is different.
Where's My Model Number?
A real technician needs your model number to nail the diagnosis and bring the right part. Here's where it hides — snap a photo when you find it.

The 4-Option Technician Decision Report
After your $50 Quick Check (or $100 in-home diagnostic), a real technician — not a chatbot — reviews your model, video, and symptoms. They build a Technician Decision Report with four honest options:
You pick which option works for you. No surprises, no hidden costs. We don't share specific part numbers — we source the parts ourselves and ship them directly to your door, so you never have to hunt for the right SKU.
What Will This Cost?
Pick the likely repair to see our flat labor price next to what most shops charge all-in. The exact part price comes after a quick diagnosis — you'll see the real number.
