I have a Carrier 58PAV090 that is about 7 years old. It wouldn’t turn on (althought it has worked this season), so I pulled the two panels and then put them back on. It tries to start up shuts down, here is what happens:
- -main blower runs
- -inducer blower runs
- -glowing igniter glows
- -gas kicks on and the 4 burners light, but then after a couple seconds it shuts off.
- -it “trys” to light 3-4 more times, then stops.
The red light flashes and shows a code #14 (below). I cleaned the “flame sensor” with steel wool, as recommended on the sticker and recommendation for error #34, and even swapped the flame sensor with my duplicate furnace in the downstairs, but with the same results on the first furnace.
In summary it lights, but then shuts off for some reason (I'm assuming that it must be "sensing" that something isn't right and shuts down for saftey reasons). Any suggestions? Thanks in advance.
Here is what the sticker on the panel says about these errors: #14 – IGNITION LOCKOUT – Control will auto reset after three hours. Refer to #34.
#34-IGNITION PROVING FAILURE – Control will try three more times before lockout #14 occurs. If flame signal lost after trial for ignition period, blower will come on for 90 second recycles delay. Check for
(and then gives suggestions to fix this error).
