Water heater inducer motor woes
I have a GSW direct vent water tank that has been operating flawlessly since installed new 2 yrs ago. Yesterday, it shut down, codes indicating a pressure/venting problem. I removed the flue (2 inch PVC, about a 13 ft run with 3 elbows) and tank worked again. No problem, I thought, blockage in the flue. I took it all apart, no blockages, and attached it back. Same problem. Took apart the blower motor, cleaned all the fins, ran a wire through the pressure switch port, tested the pressure switch and all looked ok. Hooked up 1/2 the flue, with all the elbows, tank still worked ok. Hooked up the other 1/2 exhausting to the outside, and it quit again. The second half is about 6 ft of pvc with a 45 degree on the exhaust end, with no rodent screen.
I notice that with the inducer motor running, there really doesn't seem to be a lot of suction, ie a glop of spit on the end doesn't really get sucked in. but obviously it's enough because the pressure switch operates until the second half of the flue is hooked up....I'm at my wit's end...Any ideas anyone?? Thanks in advance.
