Friedrich MR09Y3H Control Board
The system will cease to activate unless the control board is accurately installed and configured. The Friedrich MR09Y3H control board is created to control the gas valve, the ignition igniter, most sensors and the blower all at once. A matching board must have a matching part number consistent with both the brand and model of the system you have installed. It is imperative that you select wisely when you are choosing a replacement board because of the many variances of brands, models and types of systems.
General indicators that your primary control board needs replacing
- The control board has to be turned off and back on a lot for the system to operate once again
- There seems to be flashing code lit up on the board
- The whole unit refuses to do anything properly
