Mitsubishi MS12TN Control Board
The Mitsubishi MS12TN control board is created to operate the gas valve, the ignition igniter, the flame sensor and the blower all at once. Your system definitely will not function without the board in place and connected. You must be careful when you are deciding on a replacement due to so many small differences in brands, models and types of systems. The board that you will choose will have a matching part number that will fit in both the brand and model of your particular system.
Major signs your primary control board is in dire straights
- The whole system has to be powered down and back up rather frequently for the system to continue working
- Entire unit will not function at all
- There seems to be a strange code lit up on the circuit board

Before buying or purchasing a new Mitsubishi MS12TN replacement part do your best and double check the correct model as well as make a visual comparison so that you are positive that the right control board is the one being purchased. You do not need to install the replacement part alone. Locate a pro locally to do the job for you.
