The short answer
Most Cordova refrigerator noise is a fouled or contacting part rather than a failing one, and almost all of it is identified without a tool by noticing when the sound starts and stops. On this class it is usually the propane burner roaring, ticking or cycling, with refrigerant tubing resting against the cabinet shell next to rule out.
What you actually observe
- A roar or a rapid ticking from the outside access panel — On an absorption unit that panel is where the noise lives.
- A noise loud enough to hear from another room at night — Background noise masks it all day, which is why these faults are reported at night.
- NEAR MISS: the noise comes with a cabinet that is no longer cold — Then the noise is a symptom of a cooling failure and that is the page to read instead.
The causes, most likely first on this brand
- The propane burner roaring, ticking or cycling — Ranked first on a Cordova unit: there is no compressor and no cabinet fan on this design, so nearly every noise it makes comes from the burner behind the outside panel.
- Refrigerant tubing resting against the cabinet shell — A line that has shifted into contact with sheet metal turns an ordinary running vibration into a buzz that seems to come from everywhere. Ranked second here: the absorption coils are a rigid assembly that rings when anything touches it.
- A cabinet out of level or touching the joinery beside it — Ranked third here: a unit off level does not rattle so much as gurgle differently, and owners report that as a noise.
- A loose or dry drain pan under the cabinet — Ranked fourth here: last, and on this design it is a drain tube to the outside rather than a pan.
Check in this order, and why this order
- Open the outside access panel and listen with the unit on gas, then again on shore power — A noise present on gas and absent on electric is the burner and nothing else.
- Have someone press lightly on suspect tubing at the back while the unit runs — A buzz that stops under a finger is a contact point, and that is all it is.
- Push gently on each top corner and see whether the noise changes — A sound that shifts under a hand is a mounting problem and not a component problem.
What an owner can safely check
- Run the unit on shore power for a day and listen — A quiet day on electric localises the fault to the gas side without a tool.
About 30 min
- Level the cabinet on its front feet and make a finger's gap to the units beside it — A spirit level front to back and side to side settles this in a few minutes.
Tools: spirit level, spannerAbout 20 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 or the cabinet is pulled out: a capacitor can hold a charge after the power is off. Fan blades keep turning after the motor stops and their edges are sharp. A full cabinet is heavy and top-loaded, so empty it before you move it and get help rather than walking it on a corner.
When to call a technician
Call once the owner checks are clean and the noise is clearly inside the cabinet, because a fan motor or a compressor mount needs panels off and a meter. Call sooner if the noise is a grinding or a scraping, or if it arrived alongside a cabinet that is no longer cold, since those two together point at a fault that is still getting 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. Component part numbers, fan specifications and hinge hardware all change from build to build and are 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.
