What To Know
- If your RV is running on battery power, a low battery can cause the refrigerator to malfunction and the light to blink.
- If the refrigerator is set to a temperature that is too cold, it may overcool and cause the light to blink.
- If the compressor is overloaded due to excessive cooling or other issues, it may trip the overload relay and cause the light to blink.
RV refrigerators are essential appliances that keep food and beverages cold while you’re on the road. However, when the refrigerator light starts blinking, it can be a cause for concern. Understanding the reasons behind this blinking light is crucial for ensuring the proper functioning of your RV refrigerator.
Causes of Blinking Refrigerator Light
1. Power Source Issues
- Loose Connections: Check the electrical connections to the refrigerator, including the power cord and the connection to the RV’s electrical system. Loose connections can cause intermittent power, leading to the light blinking.
- Low Battery: If your RV is running on battery power, a low battery can cause the refrigerator to malfunction and the light to blink.
2. Temperature Fluctuations
- Excessive Cooling: If the refrigerator is set to a temperature that is too cold, it may overcool and cause the light to blink.
- Insufficient Cooling: On the other hand, if the refrigerator is not cooling sufficiently, the light may also blink to indicate a problem.
3. Sensor Malfunctions
- Defrost Sensor: A faulty defrost sensor can prevent the refrigerator from defrosting properly, leading to ice buildup and blinking lights.
- Temperature Sensor: A malfunctioning temperature sensor can give inaccurate readings, causing the refrigerator to operate erratically and the light to blink.
4. Compressor Problems
- Starting Capacitor: A faulty starting capacitor can prevent the compressor from starting properly, causing the light to blink.
- Compressor Overload: If the compressor is overloaded due to excessive cooling or other issues, it may trip the overload relay and cause the light to blink.
5. Other Issues
- Door Ajar: An open or partially closed refrigerator door can prevent the refrigerator from cooling properly and cause the light to blink.
- Blockages: Obstructions in the refrigerator’s vents or coils can restrict airflow and cause the light to blink.
How to Fix a Blinking Refrigerator Light
1. Check Power Source
- Tighten any loose electrical connections.
- Charge or replace the RV battery if necessary.
2. Adjust Temperature Settings
- Set the refrigerator to an appropriate temperature that is not too cold or too warm.
3. Inspect Sensors
- Test the defrost sensor for continuity using a multimeter.
- Check the temperature sensor for accurate readings using a thermometer.
4. Troubleshoot Compressor
- Check the starting capacitor for continuity using a multimeter.
- Reset the compressor overload relay if tripped.
5. Resolve Other Issues
- Ensure that the refrigerator door is closed properly.
- Clear any blockages in the vents or coils.
Troubleshooting Tips
- Unplug the Refrigerator: Unplug the refrigerator for 10 minutes to reset it.
- Check the Fuse: Inspect the fuse in the refrigerator’s electrical panel and replace it if blown.
- Contact a Professional: If you’re unable to resolve the issue yourself, contact an RV technician for assistance.
