What is happening, in three sentences
A warm PDR refrigerator with the compressor running is a cooling-path fault, not a power fault, and that narrows the list to four candidates. Two of them are conditions rather than broken parts — where the cabinet sits and how the door closes — and both are free to exclude. A refrigerator holds food safely at 40 °F (4 °C) or below, so use that as the target rather than a guess about how cold the box feels.
What you actually observe
- Condensation or sweating around the door frame — Warm room air is reaching the cold surface, and the seal is the usual route.
- The freezer section still works but the fresh-food section does not — Cold is being made and not distributed, which points at the air path rather than the sealed system.
- The back or the side of the cabinet is hot rather than warm — The condenser is trying to shed heat into air that is not moving past it.
- NEAR MISS — the cabinet is warm and the unit is completely silent — That is a no-power or start-relay fault rather than a cooling fault, and it is a different article: check the socket, the cord and the breaker first.
The ranked causes for this family
- Evaporator iced over, so the air path is blocked — Frost belongs on the evaporator; a solid sheet across it does not. Ranked first on PDR: every model under this stem has the part, so it is the one cause that cannot be excluded by knowing which code you own.
- Door seal not sealing, or the door not pulling itself shut — A gasket that has taken a set, a door that has dropped on its hinge, or a shelf holding the door open by a fraction all let room air in faster than the machine can take heat out. Ranked second because it explains the cases the first cause does not, and because on this family the two are checked from the same side of the cabinet.
- Evaporator or condenser fan not running — Either fan stopping produces a warm cabinet: without the evaporator fan the cold stays on the coil, and without the condenser fan the heat stays in the coil. Ranked third here. It is the point where an owner diagnosis starts needing tools, which is also the point where the value of carrying on drops.
What to check first, second, third
- Work from the outside of the cabinet inward — Everything on the outside is visible; everything on the inside needs the machine emptied or opened. Doing it in the other order is how an afternoon disappears.
- Look for a frost sheet on the freezer rear wall — A solid layer rather than a dusting confirms the airflow cause before anything is dismantled.
- Close the door on a strip of paper and pull — Do it at four points around the frame. A strip that slides out without resistance is the leak.
- Listen at the cabinet for each fan in turn — The condenser fan runs whenever the compressor does; the evaporator fan stops with the door switch, so hold the switch in to hear it.
Isolate the machine first
Safety
Pull the plug or open the breaker before any panel comes off — a capacitor can hold a charge after the power is off. Pulling a PDR cabinet out to reach the back is the other half of the hazard: it is a heavy, top-loaded box on a hard floor, so walk it out rather than dragging it, and keep the door shut while it moves so the weight stays where you expect it.

Where the owner fix stops
Stop and call when the next step would be a panel, a meter or a gauge. On a cabinet this size the components sit close together and a probe in the wrong place shorts something that was not broken when you started.
