Learning About Some of the Prominent Factors That Can Contribute to Airflow Problems in RV Air Conditioners
Problems that RV air conditioners may develop include many which are common for most appliances, and include the following. Here are some common reasons why your air conditioner may not be blowing air:
- Power Supply Issues: Disruptions in the supply voltage hamper the working of the AC.
- Blocked Air Filters: Dusty filters reduce the air flow and may lead to cutting off of your AC system.
- Motor Malfunction: The motor not working can hinder the movement of the fan No working motor will hamper the working of the fan
- Frozen Evaporator Coils: When coils are frosted, they don’t allow fresh air to flow through hence act as an impediment to airflow.
- Thermostat Problems: Sometimes the thermostat can go bad and this cannot allow the air conditioning system to blow air.
Step-By-Step Guide to Fixing Your Monaco RV Roof Air Conditioner
All of the aforementioned problems can be fixed using a structured trouble shooting method. Here are the steps to take:
Step 1: Check the Power Source
- Inspect the Breaker: Make sure that the breaker of the air conditioner is not ‘jumpered’. Reset if necessary.
- Examine Fuses: Press a button that points towards the blown fuse in the control panel then replace the fuse if it is blown.
- Test the Outlet: You can use a multimeter to check if power is getting to the air conditioner if at all is possible.
Step 2: Clean or Replace Air Filters
- Remove the Filter: Very gently removing the air filter from the AC unit.
- Clean the Filter: Mild soap and water should be used when washing reusable filters. Single-use filters should be replaced by new ones.
- Reinstall Filter: Make sure that the filter is totally dry before place it back again in the AC unit.
Step 3: Check and Clean the Evaporator Coils
Frozen or dirty coils are a common culprit for airflow issues. Here’s how to address this:
- Turn Off the AC: Allow the unit to sit for an hour to defrost if it’s frozen.
- Access the Coils: Remove the AC cover to access the evaporator coils.
- Clean with Coil Cleaner: Use a non-abrasive coil cleaner to remove dirt and debris.
- Inspect for Damage: Check for any signs of coil damage, which may require a professional.
Step 4: Inspect the Motor and Fan
- Listen for Motor Sounds: Turn on the AC and listen for humming, grinding, or other unusual sounds.
- Inspect the Fan Blades: If blades are obstructed or damaged, they may need cleaning or replacement.
- Test Motor Functionality: If the motor doesn’t engage, it may be faulty and need replacement.
