Carrier 50ZH Control Board
Your system definitely will not be able to function lest the circuit board is installed as it should be according to the manufacturer. The control board is created to regulate everything including the gas valve, the ignition igniter, most sensors as well as the blower all at once. You should always be careful when choosing a control board due to variances between brand and air handler types. The chosen circuit board is supposed to have a part number that matches both the brand and specific model of the unit you have installed.
What are some hints that my main circuit board really needs to be replaced?
- Heat or AC unit is unable to initialize correctly
- There may be lit up error code revealed on the control board
- The whole system has to be turned off and back on all the time in order to run
