Quick question..

My Bryant gas furnace decided not to come on.. thermostat clicked, but nothing happened.

Checked error code.

Initial error code 23, with no inducer fan coming on, just an error code.


Disconnected one of the wires on the pressure switch... re tried. Inducer fan came on and then got error code 31.

Turned everything off again... re connected both wires to pressure switch, tapped on the round plastic pressure switch a few times....

Re tried everything, bam... it worked heater turned on... great..

Now, the question.

Does this switch freeze up, did it just fix itself... should I install a new one?

Thanks
