Mitsubishi MSZ-A18YV Control Board
Most systems will not run at all lest the circuit board is accurately installed and configured. The Mitsubishi MSZ-A18YV control board is made to direct the gas valve, the igniter, all the various sensors and the blower all in one unit. You should always be careful while selecting a replacement because of the many variances of heating and cooling systems. The control board picked should be compatible with both the brand and model of air handler system you have.
Major indications your primary control board will need replacing
- When turned on, there is a certain error code revealed somewhere on the circuit board
- AC or heating system cannot go period
- The entire system needs to be reset many times a week for the system to continue working
