Carrier 48XZ048130300 Control Board
The control board is created to control the gas valve, the igniter, all the sensors as well as the air circulator all at once. It is impossible for your furnace or air handler to even activate lest the main control board is installed. You must be careful when choosing a control board due to differences in models and types. Any control board you choose should match both the brand and model of HVAC system.
Easy warnings your control board needs a replacement ASAP
- System has flashing code being shown somewhere on the board
- Your HVAC unit does not function at all
- Everything has to be powered down and back up a lot for it to work
