Fan Prover did not re-close after 10 minutes of venter operation.
What this means – During a run cycle the prover opened. The venter will run for 10 minutes trying to re-make the prover switch, which it was unable to do.
Possible Solutions – Verify appliance and venter draft settings are properly adjusted.
-Check P1 & P2 prover circuit wiring for loose connections.
-Clean prover sensing tube and blower wheel.
-Block wind from hitting termination of vent.
