    Turned out not needed. I installed it and left it in. The Honeywell smart valve was bad. This board had a broken plastic surround at the positive terminal. It did not affect the function. Very good transaction and supplier,

    Fits and works!

    This part wasn't exactly the same as I thought I was buying (ST9120C4057) but it is compatible and matches all the same connectors as my previous board.the only thing it did not match up with is the pins to clamp down into place on the furnace. I used a hot glue gun to hold the board in place. I applied glue inside the small tin cups then inserted them into 2 of 4 pins that lined up seems to hold just fine. Also just saying I'm not an AC guy just some Joe fixing my issue.

  • Reliable circuit board. Fast fix

    I was able to quickly install this board moving one wired at I'm making sure that the connections were the same. All numbers matched perfectly and took about 15 minutes to change out the circuit board. HVAC company wanted $150 for the board Plus service fee and call. Fix myself for 35..

  • Solved the problem on an existing furnace.

    Direct, identical replacement, plug and play, works like a champ! Arrived as ordered, installed on my daughter's furnace, repair complete. HVAC "pro" identified problem as the gas valve, was way off...faulty ground on the old circuit board was the issue, and this replacement solved the issue upon installation.
