The Dometic RV Fridge is a great device, but like all electronics, it sometimes has its issues. If your Dometic RV fridge is not working, take a look at this troubleshooting guide.
We’ve collected answers to the most frequent reasons you’ll see Dometic RV Fridge not working and explained them in plain language for easy troubleshooting.
Quick Fix
To troubleshoot a Dometic RV fridge, check the power source and thermostat settings, verify proper ventilation, ensure the fridge is level, clean burner and vents, and inspect the cooling unit for damage or leaks.
Dometic Fridge Issues and Symptoms
Diagnosing Dometic fridge issues begins with identifying the symptoms.
You’ve likely noticed the check light has come on after a power outage, indicating a problem with your Dometic RV fridge. Cycling the fridge off and on doesn’t resolve the issue, suggesting a more complex problem.
The fridge won’t stay on when set to auto, tripping after a 30-count, which may be related to a faulty circuit board or relay.
When you check the freezer, the floor feels cold to the touch but not freezing, and the fridge isn’t cold, pointing to a potential issue with the cooling unit.
Additionally, the fridge may not be firing off on gas mode, causing the check light to come on, which could be due to a blockage in the burner tube or faulty electrode.
Troubleshooting Steps and Diagnostic Tests
You’ll start by ruling out fridge power source issues by plugging the unit into an outside power source to confirm good AC voltage and 12V DC battery voltage.
Next, inspect the burner tube for blockages and clean it out to guarantee proper propane flow and ignition.
From there, you’ll perform electrical system checks, including inspecting the outlet and breakers inside the RV, to isolate the issue and determine the root cause of the problem.
Fridge Power Source Issues
When your Dometic RV fridge fails to operate, the power source is a good place to start troubleshooting, as it’s often the culprit behind the issue.
First, verify the fridge is receiving power from the 12V DC or 120V AC source. Check the circuit breaker or fuse box to confirm the circuit hasn’t tripped or blown. If you’re using gas, verify the propane tank is turned on and there are no leaks in the system.
Next, inspect the circuit board for signs of damage or corrosion. Check the power cord and connections for frays or loose connections. If you’ve checked all these potential issues and the fridge still won’t turn on, it’s likely a more complex problem requiring professional attention.
Propane Ignition Problems
Inspect your Dometic RV fridge’s propane ignition system if it fails to ignite or stays lit only briefly.
Check the pilot light for a weak or yellow flame, indicating improper air-to-gas mixture. Guarantee the gas valve is fully open, and no blockages exist in the propane line. Verify the propane tank has sufficient fuel and is turned on.
If your Dometic fridge has an electric ignition, certify it’s receiving power. Consult your owner’s manual for specific troubleshooting steps.
Perform a leak test on the gas valve and propane line to rule out any leaks. If issues persist, consider replacing the gas valve or having a professional inspect the system.
Electrical System Checks
Verify that your Dometic RV fridge’s electrical system is receiving power by checking the circuit breaker or fuse box.
Certify that it’s not tripped or blown. If you’re connected to shore power, check the power source and AC voltage at the RV’s electrical hookup.
- Check the fridge’s electrical connections to confirm they’re secure and not corroded.
- Use a multimeter to measure the voltage at the fridge’s electrical terminals.
- Verify that the fridge’s circuit breaker or fuse hasn’t tripped or blown due to a power surge.
- If you’ve recently experienced a power outage, try resetting the fridge’s electrical system by turning it off and on again.
Circuit Board and Electrical Issues
When your Dometic RV fridge fails to light off on propane, the circuit board is a likely culprit, and you’ll need to replace the entire board, which can cost between $150-$250.
If the relay that senses AC power on the board has failed, you can’t replace it individually, and a new board is your only option. You’ll need to diagnose whether the relay failure is the issue, and then consider your replacement options, including sourcing parts from reputable suppliers like The Dometic Guy online.
Relay Failure Diagnosis
Your Dometic RV fridge‘s circuit board is the brain of the operation, and a faulty relay can bring the whole system to a grinding halt.
If the relay that senses AC power on the board fails, you won’t be able to switch to AC power, and replacement of the entire board may be necessary.
- A faulty relay can prevent the fridge from lighting off on propane; to diagnose, unplug the unit and check if LP comes online.
- If the LP gas comes on when city power is removed, the power board is working.
- Issues with the power board can be diagnosed by unplugging the P-2 connector and seeing if the fridge cools.
The Dometic Guy online is a good source for replacement circuit boards and expert advice on diagnosing relay failure.
Board Replacement Options
One faulty circuit board can bring your Dometic RV fridge to a standstill, and replacing it’s often the most effective solution.
If your fridge fails to cool, you may need to replace the entire circuit board, which can cost between $150-$250. You can’t replace the relay that senses AC power on its own, so the whole board needs to go.
Consider the Dinosaur Electronics circuit board as a replacement option.
During troubleshooting, try unplugging the P-2 connector and letting the fridge sit for a few hours to see if it cools.
If the propane comes on when city power is removed, the power board is working, and the issue lies elsewhere in the electrical system.
Consult your service manual or a professional RV technician for further guidance on replacing electrical components, including the circuit board.

- Temperature fluctuations: Verify that the fridge is level and properly installed to prevent uneven cooling.
- Failure to cool: Check the fridge’s thermostat and temperature settings to guarantee they’re set correctly.
Leveling and Setup Considerations
Proper leveling and setup of your Dometic RV fridge are vital to its peak performance.
You’ll want to guarantee the fridge is installed level and plumb to prevent uneven cooling, decreased efficiency, and potential damage.
When setting up your fridge, you’re looking around for a spot with adequate ventilation, as poor airflow can hinder performance.
Check the back side of the fridge for any obstructions that might impede air circulation.
Make sure the side of the fridge is clear of any blockages, allowing for proper heat dissipation.
Take the time to double-check your setup, as improper installation can lead to a host of issues down the line.
Safety Precautions and Best Practices
Caution is paramount when operating your Dometic RV fridge, as improper use can lead to accidents, injuries, and even fatalities.
To guarantee safe and trouble-free operation, you must follow essential safety precautions and best practices.
- Always check the fuses before attempting to troubleshoot or repair your fridge to avoid electrical shocks or fires.
- Be aware of any unusual smells, such as ammonia, which can indicate a refrigerant leak, and take immediate action to ventilate the area and contact a professional.
- Certify the fridge is properly installed, leveled, and secured to prevent tipping or shifting during travel.
- In case of a power outage, wait for the fridge to stabilize before opening the door, as the light would come back on when the power is restored, indicating the fridge is working properly.
Replacement Costs and Considerations
When your Dometic RV fridge malfunctions, getting it back up and running quickly is vital to maintaining a comfortable and safe living space.
If repairs aren’t feasible, you’ll need to weigh replacement costs, which can range from $1,000 to $3,000 depending on size, style, and configuration. Larger units cost more than compact ones, so size is a significant factor.
You may opt for a refurbished or second-hand fridge, but their cost-effectiveness is hard to predict. New units usually come with a warranty, which may be covered by your RV insurance policy or the RV’s warranty. Be sure to check your policy, as appliance coverage may require an additional premium.
