To thaw a frozen evaporator, the first step is to turn off the air conditioning system. This can be done by shutting off the unit at the circuit breaker. By doing this, you are allowing the coils to thaw out naturally without any additional cooling.
It’s important to note that the time it takes for the coils to thaw completely can vary. In general, it could take up to 24 hours for the coils to thaw completely. During this time, it’s best to avoid turning the system back on as it could cause further damage to the unit.
While the coils are thawing, you may notice some water dripping from the unit. This is normal and indicates that the thawing process is taking place. It’s a good idea to place a towel or bucket under the unit to catch any excess water and prevent any water damage to your floors or walls.
During this time, it’s also important to check the air filters. If they are dirty or clogged, they could be contributing to the freezing of the coils. If necessary, clean or replace the filters to ensure proper airflow and prevent future freezing.
After the coils have thawed completely, you can turn the air conditioning system back on. However, it’s important to monitor the unit closely to ensure that it is functioning properly and not freezing up again. If you notice any issues or the coils continue to freeze, it may be necessary to contact a professional technician to diagnose and fix the problem.
In summary, to thaw a frozen evaporator, turn off the air conditioning system at the circuit breaker and allow the coils to thaw naturally for up to 24 hours. Check and clean or replace the air filters if necessary. Once the coils have thawed completely, turn the system back on and monitor it closely for any further issues.
