Friedrich MW18Y3FM Control Board
Your system definitely will not operate without the board configured and seated properly. The control board is constructed to operate everything including the gas valve, the ignition igniter, the flame sensor and the blower all together. It is imperative that you select wisely while picking a new replacement board due to variances between heating and cooling systems. The proper control board should have part numbers that match the brand and the model of the unit in question.
What are some indications that my Friedrich control board needs replacing?
- There may be a numbered error code indicated on the board
- The control board has to be reset all the time for the heating or cooling to kick in
- The AC or furnace ceases to initialize properly
