having problems with Burnham 205NCL-TEI2. I've replaced damper assembly & cable, thermocouple, TACO box and transformer. Pilot will stay lit,
When electric is restored to unit >>> pilot stays lit, NO ZONES are calling for heat but burner ignites and cuts off within a few seconds and continually repeats this cycle, damper cycles continuously. Is my valve "sticking" and possibly bad? I've replaced all other parts...
vent switch & flame rollout switch ohm'd out OK
