Goodman GCV90704CXA-P1257803F Control Board
The Goodman GCV90704CXA-P1257803F control board is designed to operate everything including the gas valve, the igniter, all the sensors and the blower all in one unit. Most systems will not run at all unless this important circuit board is installed as it should be according to the manufacturer. You should always be careful when you are choosing a replacement board due to so many small differences in systems. The board you choose must be compatible with both the brand and specific model of HVAC system.
Indications your control board will not live much longer
- The whole unit ceases to do anything whatsoever
- When turned on, there is some sort of error code being shown somewhere on the board
- The HVAC system has to be turned off and back on quite frequently for the heating or cooling to kick in
