Haier HR30D2VAR Control Board
Heating and cooling systems will not even operate lest the main control board is configured and seated properly. The Haier HR30D2VAR control board is designed to oversee the gas valve, the igniter, most sensors and the blower all together. A matching board should have a replacement part number that matches the brand and the model of furnace or air handler you have. It is of utmost importance when you are deciding on a replacement due to the many differences between models and types.

- When turned on, there is a strange type of error code indicated on the front of the control board
