One reason your RV AC compressor might shut off after 2-3 minutes is low refrigerant levels. The refrigerant is crucial for cooling. If it’s low, the compressor can’t work efficiently. Let’s dive into how to check and refill refrigerant levels.
Low Refrigerant Symptoms
Low refrigerant can cause various issues. Here are some symptoms to watch for:
- Warm air: The AC blows warm or less cool air.
- Short cycles: The compressor runs for a short time and then shuts off.
- Ice buildup: Ice forms on the evaporator coils.
- Hissing sounds: You hear hissing or bubbling noises.
If you notice these symptoms, check the refrigerant levels.
How To Refill
Refilling refrigerant is a task that needs care. Here’s a simple guide:
- Turn off the AC: Ensure the unit is off before starting.
- Locate the ports: Find the low-pressure port on the AC unit.
- Attach the gauge: Connect the refrigerant gauge to the low-pressure port.
- Check levels: Read the gauge to see if the refrigerant is low.
