- Evaporator Fan Malfunction: If the evaporator fan fails it could be due to an obstruction that is keeping it from rotating, or a broken wire could have disconnected the evaporator fan from the thermostat. Either could cause air conditioning frost build-up to occur.
- Decreased Air Flow: Without proper air circulation an AC will begin to ice up quickly around the condenser or evaporator coils. This could be the result of a blocked return duct vent, dirty air filters or dirty, blocked coils. Whatever the culprit, a decrease in air flow will cause the AC to work overtime, resulting in frost buildup.
- Unreasonable Thermostat Settings: If a thermostat is set to a temperature that is too low it can cause the AC to work continually without ever reaching that desired temperature. Generally air conditioners can only work up to a twenty degree temperature difference from outside air, so if your AC is set to 70 while the temp outside is 100, you’ll never reach the desired temperature.
- Blower Failure: Blowers that fail completely or which run at the wrong speed can cause AC icing to occur.
- Low Refrigerant Levels or Charge: Having too little refrigerant charge can cause air conditioning frost build-up to occur. It could be that the AC has been running for too long without a break which has caused refrigerant levels to decrease, or that there is a slow leak in the refrigerant line which needs to be fixed.
