The short answer
On a Tremier refrigerator, this symptom is almost never a dead compressor. It is airflow: something is stopping cold air from moving, or stopping heat from leaving. Across a trade-name range the control and sealing parts are shared while the cabinet size is not, so a fault reads the same on a small unit as on a large one.
What you are actually seeing
- The freezer side is still cold while the fresh-food side is not — Cold is being made but not delivered, which points at airflow rather than at the compressor.
- The cabinet is warm but the unit is plainly running — You can hear it working; the air inside is not cold.
- NEAR MISS — only the ice maker has stopped while the food is cold — That is an ice production fault and it is covered on its own page.
Causes, most likely first on this refrigerator
- Heat rejection choked — dust on the coil or no clear air path around it — Ranked first on Tremier: it is the one cause that the owner can both confirm and fix in a quarter of an hour, and on this platform it is the commonest single reason a cabinet runs without cooling. On this one, remember that sizes differ across the range but the sealing and control parts do not, so the fault reads the same on all of them.
- Frosted evaporator from a defrost cycle that has stalled — Second: this is the classic slow failure on shared platforms: the defrost stops working long before anything sounds wrong, and the ice builds quietly.
- Ambient conditions or loading the cabinet was never rated for — Third: a garage in summer, a cabinet stuffed to the back wall, or an internal vent covered by a box will each produce this symptom with nothing broken.
- A fault on the sealed refrigerant system — Last, and that is the point of the order: it is the least common of the causes and the only one that is not an owner fix, so checking it first wastes the cheap checks above.
Check in this order, and why
- First — look at the condenser and its air path — grille, back panel or the space around the cabinet — It is free, it needs no tools, and it decides whether anything else on this list is worth checking.
- Then — look at the back wall of the freezer compartment for a sheet of frost — A sheet rather than a light dusting confirms the airflow story and rules out the sealed system.
- Only then — feel whether the condenser is warm and listen for the compressor — Only worth doing once everything above is clean, because it changes nothing an owner can act on, which is why it comes after everything above it.
What an owner can safely check
- Clear the condenser coil and the air path around it — Pull the front grille or the lower back panel and vacuum the fins clean, then check nothing is stacked against the cabinet or over the vent.
Tools: vacuum, soft brushAbout 15 min
- Clear the internal vents and give the cabinet its clearance — Move packaging off the vents at the back and top of the compartment, and pull the unit far enough from the wall that air can rise behind it.
About 10 min
- STOP at the first step that needs a meter on live terminals — That is where an owner check ends and a service visit begins, and nothing above this line needs one.
Before you open anything
Safety
Unplug the cabinet or switch off its breaker before you take any panel off — a capacitor can hold a charge after the power is off. Do not tape, wedge or otherwise defeat a door switch to keep a fan running while you look: the switch is there so that a hand in the cabinet cannot meet a spinning blade. Refrigerant work is licensed work; nothing on the sealed system is an owner job.
When it stops being an owner job
Call once the air path, the gasket and the fan check are all clean, or straight away if the cabinet is silent, if the compressor buzzes and stops repeatedly, or if you can see oil around the tubing at the back. Oil outside the tubing means the sealed system is open, and every hour it runs after that costs more to put right.

This page is written for the Tremier refrigerator as a class, not for one family or one model line. Where a family-specific page exists for your unit it is linked above and it is the more specific answer. Deliberately not here: part numbers, wiring colours, torque figures and any measured value, all of which differ by family.
