Hello,

My name is ***** ***** I will do my best to assist you. I am looking over your question now and will respond shortly.

Expert:  BillyHvac replied 1 month ago.

Customer: replied 1 month ago.
Have tried the component test and nothing happens
Expert:  BillyHvac replied 1 month ago.

what happens after the 12 code?

solid light or direct to another code...the 12 should only be 90 seconds

Customer: replied 1 month ago.
The 12 stays on all the time
Expert:  BillyHvac replied 1 month ago.

then the circuit board itself is defective.

even if the code were reversed and was 21 the board would still be bad.

The only fix is to replace the circuit board.

Not worried...

Being old has some advantages.....
