RV Refrigerator Repair in Guntersville, Alabama
Not cooling, not switching power sources, or clicking without igniting — a dead RV fridge ruins a trip and spoils everything in it. We diagnose the actual problem and fix it right.
Diagnosis First. Every Time.
An RV refrigerator that won't cool has failed in a specific way — a burner that won't light, a heating element that burned out, a cooling unit that stopped working, or a control board not sending the right signals. The symptom looks the same from the outside regardless of what caused it, but the repair is completely different depending on the actual failure.
We test each component to find exactly where the system breaks down before recommending anything. You know what failed, what it takes to repair or replace it, and what it costs — before we start any work.
No parts swapping hoping something works. No recommending a new fridge when a heating element fixes the problem. Diagnosis first.
RV Refrigerator Problems We Fix
These are the failures we see most often — and how we trace each one to its cause.
Not cooling on any power source
When an absorption fridge fails to cool on both propane and electric, the cooling unit itself is the likely cause. The ammonia solution that drives the cooling process can separate over time or from running out of level — once separated, no heat source repair will fix it. We confirm cooling unit failure before recommending replacement, because other causes can produce the same symptom.
Works on propane, not on electric
The propane burner and the 120V electric heating element are independent heat sources. If the unit cools on propane but won't switch to electric, the AC heating element has likely failed — a straightforward repair. First confirm the outlet feeding the fridge has power and the fridge breaker hasn't tripped. If power is present but the fridge won't run on AC, the element or control board is the cause.
Works on electric, not on propane
A propane burner that won't light is one of the most common refrigerator repairs. Common causes: a dirty or failed ignitor, a corroded electrode, a blocked burner orifice, or a failed gas valve. Absorption fridges need 12V power for ignition even on propane — a weak battery can prevent the ignitor from firing consistently. We check the full ignition sequence to find where it's breaking down.
Cooling but not cold enough
An absorption fridge that runs but doesn't get cold enough is often a ventilation problem — the condenser coils need airflow to reject heat, and if blocked, cooling capacity drops significantly. A partially failed cooling unit or a thermostat not reading temperature correctly can also cause weak cooling. We check ventilation, temperature at multiple points, and the control system before concluding the cooling unit needs replacement.
Clicking, beeping, or error codes
An absorption fridge that clicks repeatedly without igniting has exhausted its ignition attempts and locked out. Check that propane is on and battery voltage is above 10.5V — two of the most common causes. If both are fine, the ignitor or flame sensor is likely the cause. Error codes on the control panel narrow the diagnosis significantly — we read the fault history before touching anything.
Compressor fridge not cooling
Compressor refrigerators (GE, Furrion, LG, Everchill, and others) fail more like home refrigerators. A compressor that won't start, a thermostat that's lost calibration, or a control board fault are the most common causes. We also check that the inverter or shore power connection is delivering the voltage the fridge needs — an undersized inverter causes erratic compressor behavior.
Two Types of RV Refrigerator — Very Different Systems
Knowing which type you have tells us where to start. The diagnosis path for each is completely different.
Absorption Refrigerators
Use heat — from propane or a 120V electric element — to drive a cooling process based on ammonia and water cycling through a sealed system. No compressor. Quiet. Run on either energy source. Only two manufacturers make absorption refrigerators: Dometic and Norcold.
Important: Absorption fridges require 12V battery power for the control board and ignition regardless of whether they're running on propane or AC electric. A weak or dead battery prevents the fridge from operating even with propane and shore power connected.
Common failures: Cooling unit separation, burner and ignitor failure, heating element burnout, control board faults, thermostat issues, ventilation blockage.
Compressor Refrigerators
Work exactly like a home refrigerator — a compressor circulates refrigerant through an evaporator coil. Run on 12V DC or 120V AC only, no propane. More energy efficient than absorption units and work regardless of how level the RV is. Increasingly common in newer RVs, especially those with lithium battery and solar systems.
All RV refrigerator brands other than Dometic and Norcold use compressor technology: GE, Furrion, LG, Whirlpool, Amana, Everchill, Isotherm, and others.
Common failures: Compressor failure, thermostat drift, control board faults, insufficient inverter capacity, power delivery issues.
Repair or Replace — The Honest Answer
The right answer depends on what failed, the age of the unit, and the cost of each option. Here is how we think about it.
Repair Usually Makes Sense
Ignitor, electrode, or flame sensor failure — inexpensive parts, straightforward repair.
AC heating element burnout on a unit that otherwise runs well.
Control board replacement when the cooling unit and other components are sound.
Compressor refrigerator repairs where the unit is newer and otherwise in good condition.
Replacement Often Makes Sense
Cooling unit failure on an older absorption fridge — cooling unit cost plus labor can approach the price of a new unit.
Multiple failing components on an aging unit where total repair cost adds up.
Opportunity to switch from absorption to compressor for better efficiency with a solar or lithium setup.
Parts no longer available for a discontinued model.

RV Refrigerator Questions We Hear Every Day
The answer depends on which type of refrigerator you have. Absorption refrigerators (Dometic and Norcold) run on propane or 120V electric and need 12V power for the control board regardless of which heat source is in use. If yours works on one power source but not another, the problem is in that specific circuit. If it won't cool on any source, the cooling unit itself may have failed — a common failure in older absorption units where the ammonia solution separates. Compressor refrigerators fail more like home refrigerators: compressor, thermostat, or control board. We test each component to find the actual failure before recommending a repair or replacement.
An absorption refrigerator uses heat — from propane or an electric heating element — to drive a chemical cooling process using ammonia and water. Only two manufacturers make absorption refrigerators: Dometic and Norcold. They work without a compressor, which makes them quiet, but they are less efficient and must be reasonably level to operate correctly. A compressor refrigerator works exactly like a home refrigerator — a compressor circulates refrigerant through an evaporator coil. All brands other than Dometic and Norcold use compressor technology. Compressor refrigerators are more energy efficient and work regardless of how level the RV is, which is why they are increasingly common in newer units.
For absorption refrigerators, the key question is whether the cooling unit has failed. A cooling unit replacement can be cost-effective on a newer unit, but if the fridge is older and the control board, burner components, and cooling unit are all showing wear, replacement of the full unit is often the better investment. For compressor refrigerators, individual component repairs (compressor, thermostat, control board) are usually straightforward and worth doing on any unit that is otherwise in good condition. We give you an honest comparison of repair cost versus replacement cost based on the actual diagnosis — not a default recommendation to replace.
The propane and electric heating systems in an absorption refrigerator are independent. If the fridge cools on propane but not on 120V AC, the problem is in the AC heating element or the AC circuit feeding it — not the cooling unit itself. A failed heating element is a straightforward and relatively inexpensive repair. Check that the outlet supplying the fridge has power and that the breaker has not tripped before assuming the element has failed. If power is present at the outlet but the fridge will not switch to electric, the element or the control board is the likely cause.
We stock common replacement units and order directly from manufacturers for specific models. If your refrigerator needs replacement, we can help you identify the correct replacement for your RV's existing cutout dimensions — which matters because not all units are interchangeable without modification. We handle the diagnosis, the recommendation, the sourcing, and the installation so you get the right refrigerator installed correctly.
