  Kimberly ScottAug 10, 2025
  If your Airxcel Air Conditioner runs continuously but doesn't cool effectively, first check the air filters and blower operation, removing any airflow restrictions. Then, check for proper refrigerant charge and any possible leaks. Inspect internal components, especially the compressor, for proper operation. If the unit is undersized, consider adding additional units.

  If your Airxcel Air Conditioner isn't running, start by checking the power supply to ensure it has adequate phase and voltage. Inspect the wiring to the unit and any external breakers or fuses. Also, check the internal circuit protection devices for continuity. Verify the operation of the wall-mounted thermostat. Reset the pressure switch. Finally, check for loose wiring and component failures.

  If your Airxcel Air Conditioner is blowing fuses or tripping the circuit breaker, ensure the circuit ampacity is adequate according to Chapter 2 and correct as necessary. Check the field wiring for errors such as shorts, looseness, or improper connections. Inspect the unit's internal wiring, consulting the wiring and schematic diagrams, and test components (especially the compressor) for shorts. Also, check for excessively high or low supply voltage or phase loss (3ø only), noting voltage range limitations specific to the compressor troubleshooting section.

Why does my Airxcel Marvair MAA1018 cycle on high/low pressure?

  If your Airxcel Air Conditioner cycles on the high/low pressure limit, examine the blower assembly for proper operation and check for airflow restrictions, such as a dirty air filter. Inspect the blower motor and condenser fan. Look for any blockages or restrictions in the refrigerant circuit, especially the filter drier and capillary tube assembly. If the unit was recently serviced, check for refrigerant overcharge and evacuate/recharge to factory specifications. Finally, check the limit cutout pressures of the pressure control, which should actuate at approximately 60 PSIG (low pressure) and 650 PSIG (high pressure).
