Friedrich MW18Y3H Defrost Sensor Board
The defrost control board instructs the system to activate an important defrosting cycle which actually helps to get rid of the frost that collects on the outdoor unit. It is relayed information from a defrost sensor that can be found near the condenser, in order to agree when to begin.
Major symptoms your defrost board has to be replaced
- The defrost sequence never begins even though there is a large amount of frost that has built up
- The whole system may end up not running because of the frost issue
- The main circuit board might issue a type of error code produced by too much frost

If you are going to be buying or purchasing do your best and double check the correct model as well as make a visual inspection so that you are positive that the correct defrost sensor board is the one being purchased. HVAC pros could be quite expensive to hire so you may want to keep a lookout locally to find a good deal if you do not want to pay too much.
