Carrier 48XL-A Control Board
Heating and cooling systems will not even operate whatsoever lest the circuit board is correctly installed. The control board is made to operate the gas valve, the igniter, all the sensors as well as the air circulator all in one unit. Any control board you choose should match the model number with both the brand and specific model of HVAC system. You should always be careful while selecting a replacement due to the vast differences in heating and cooling systems.
Simple warnings that your Carrier control board is in need of replacing?
- When turned on, there is a strange type of error code indicated on the circuit board
- The entire system does not function well
- The whole system has to be turned off and back on quite often for it to run
