Customer Question

hi M Oglesby, my 58STA/STX won't light
Submitted: 1 year ago.

Do you get blinking light on the circuit board in the blower section?

Customer: replied 1 year ago.
One short, two long blinks
Expert:  BillyHvac replied 1 year ago.

That code will be present for 90 seconds..after 90 seconds the main blower stops and exhaust fan starts...then the error code will happen

Customer: replied 1 year ago.
now the light is on constantly, nothing is happening except I hear a rapid clicking sound
Expert:  BillyHvac replied 1 year ago.

and the exhaust fan starts?

Customer: replied 1 year ago.
no.
Expert:  BillyHvac replied 1 year ago.

ok that is our issue.

Now it must be determined if the exhaust motor gets power (120v)...and doesnt run.....OR...the circuit board is not sending power..

So it boils down to 2 choices..

120v at motor and no operation = bad/stuck motor

120v NOT at motor = bad circuit board
