Samsung UQB18J6WC Control Board
The Samsung UQB18J6WC control board is designed to control the gas valve, the igniter, all the sensors as well as the blower all at once. Heating and cooling systems will not even activate without this vital piece of hardware is in place and connected. You must be sure when you choose a control board due to variances between HVAC systems. A replacement board will have to match part numbers both the brand and specific model of the unit you have installed.
What are the clues to watch out for to know my main circuit board is dying?
- There seems to be a strange type of error code randomly appearing on the circuit board
- AC unit or heating unit cannot run at all
- The power to the system has to be reset repeatedly for it to work
