The short answer
The ARV roster covers a small group of closely related cabinets, and it lists two naming generations side by side, so cabinets of noticeably different ages share this page. When one compartment is cold and the other is not, the cabinet has an airflow problem rather than a cooling problem, because on cabinets of this kind the cold is made in one place and moved to the other. That single observation redirects the whole diagnosis.
What you observe on these models
- The cabinet is warm but clearly running — The compressor hum is there and the air inside is not cold.
- The freezer side is cold and the fresh-food side is not — Cold is made in one place and moved to the other.
- Frost building as a sheet on the rear interior wall — A layer rather than the usual light dusting.
- The compressor never cycles off — The cabinet is no longer reaching its set point, so the control never tells it to stop.
Causes, most likely first on the ARV line
- Frosted evaporator blocking the air path — Ranked first on this roster: frost builds quietly over weeks, which is why owners notice the temperature rather than the ice that caused it.
- Door seal not closing, or a door left ajar — Ranked second on this roster: a seal that has taken a set admits room air continuously, and a cabinet cannot out-run a steady supply of warm humid air no matter how well the rest of it is working.
- Vents blocked by stored food or an overfilled shelf — It ranks third here because it is free to correct, extremely common after a big shop, and produces exactly the one-compartment-warm pattern owners describe.
- Start components or the sealed system — Ranked last on this roster: reaching it honestly is a useful result, because it turns the question into repair or replace rather than keep looking.
- Body: Where this ranking departs from the brand-generic order is door seal not closing, which moves up on the ARV line because the roster leaves the finish and trim position unresolved on some entries, so the door and its seal are the part of the cabinet you have to confirm by eye.
Check in this order, and why
- Establish which generation of this roster you have — Two naming generations are listed together here, so cabinets of noticeably different ages share this page. Which one you own changes what a worn part is likely to be.
- Look at the rear interior wall for a frost sheet — A layer thick enough to hide the surface underneath explains the complaint on its own, and it means the defrost side is worth investigating.
- Close the door on a strip of paper at several points and pull — Anywhere the paper slides out freely is admitting air. Check the whole perimeter, not just the handle side.
- Clear the back of every shelf and find the vents — Leave a hand's width clear at the rear of each shelf, then give the cabinet a day before judging.
Before you open anything
Safety
Switch off at the breaker before any panel comes off and treat the space behind it as live until proved otherwise. Defrost with the doors open and the power off, never with a heat gun or an open flame, and never by chipping at the surface. Keep meltwater away from the supply cord.

When to call a technician
Call when a full defrost, a cleared condenser and a clean paper test have all failed to hold the cabinet for a day, because that pattern eliminates everything an owner can reach. Call sooner if only one compartment is affected and the vents are already clear, because a damper or an interior fan needs a panel off. Either way, move the perishable load first: it will not survive the diagnosis.
