Call for Heat – Unit Does Nothing
The below troubleshooting steps refer to situations where the green light on the control
board is ON and the unit does NOT operate correctly when a jumper wire is installed
between terminals R & W on the control board:
Step 1: Check for loose connections. Disconnect and reconnect all Molex plugs.
Step 2: Check to make sure there are no troubleshooting codes.
Step 3: Turn the switch to the gas valve off and on. Then leave valve on.
Step 4: If the unit still does not operate correctly, you may have a bad control board.
• If you suspect a bad control board, turn to page 23 and follow the additional
troubleshooting steps before replacing the control board.
