The short answer
A Cordova refrigerator that runs without cooling is almost never the compressor, whatever the noise suggests. On this class the fault is usually the absorption unit off level, or running on the wrong energy source, with a propane burner or electric element not actually heating next to rule out, and both are visible to an owner in minutes.
What you actually observe
- There is a faint ammonia smell or a yellow stain at the outside vent — That is the one symptom on this list that ends the diagnosis immediately.
- The freezer side is holding but the fresh-food side is not — A split like this is an airflow story rather than a cooling story.
- NEAR MISS: only the ice maker has stopped while the food stays cold — That is an ice-production fault and it is a separate page with a separate cause list.
The causes, most likely first on this brand
- The absorption unit off level, or running on the wrong energy source — An absorption cooling unit moves nothing mechanically: it relies on gravity to return liquid through the coils. Ranked first on a Cordova unit: an absorption unit circulates by gravity, so time spent parked off level stops it more often than any component failure does.
- A propane burner or electric element not actually heating — On an absorption unit the heat source drives the whole cycle. Ranked second here: the heat source drives the entire cycle here, and a sooted burner or a dead element leaves the cabinet warm with nothing audible to warn you.
- A blocked or wasp-nested roof vent and rear chimney — Ranked third here: the chimney behind the sidewall is where this design rejects its heat, and it is the first thing wasps and birds find.
- A sealed-system fault or a compressor that no longer pumps — Ranked fourth here: last, because a cooling unit that has genuinely failed usually announces itself with a yellow stain or an ammonia smell at the vent.
Check in this order, and why this order
- Check that the coach is level and confirm which energy source the unit actually selected — Both questions are answered from the control panel and the doorway, before anything is opened.
- Look for a flame at the burner on gas, then repeat the test on shore power — Cooling on one energy source and not the other localises the fault to that source's heater in one step.
- Open the outside access panel and look up the chimney — Nesting material, leaves or a bird screen packed solid is visible from the panel without removing anything.
What an owner can safely check
- Level the coach, switch the unit off for several hours, then restart it on shore power — A unit that recovers after a long rest off level was stalled rather than failed.
About 60 min
- Confirm the gas supply is open and the tank is not empty, then try the unit on shore power — This separates a supply problem from an appliance problem without any tool at all.
About 15 min
- STOP HERE if the next step needs a meter on live terminals or a panel off — That is where an owner check ends and a service call begins.
Before you open anything
Safety
Unplug the unit or switch off its breaker before any panel comes off: a capacitor can hold a charge after the power is off. Leave the door switch wired as it is, because it cuts the fan for a reason. Never chip ice off an evaporator with a tool, since the refrigerant tubing runs directly behind it.
When to call a technician
Call once the owner checks come back clean, or the moment the evidence points at the sealed system: refrigerant work is licensed work. Call immediately if you smell burning or see oil at the compressor, because that means the system is open and every further running hour makes the repair worse. Bear in mind when you decide that an RV appliance is serviced by RV dealers rather than by household appliance technicians, and the warranty usually runs through the dealer who sold the coach.

What this page does not cover
This page covers the Cordova refrigerator as a class, not one family or model line. What changes from build to build, meaning wiring colours, component test values and part numbers, is deliberately not here. Where a family or model page exists for your unit, it is the more specific answer and the one to read first.
