My furnace(an amana) seems to be stopping due to too much water in the inducer motor. If I pull the yellow plug from the motor housing, a good amount of water comes out and then the unit will work again.
After a lot of troubleshooting I noticed something. There are two drains. One is up top left near the exhaust exit and the other is at the bottom right. They drain into a reservoir. I made it so I could see each drain emptying when it was running. The one on the bottom right does not drain until the unit is turned off/stopped! This is telling me that it is not clogged(which is what I thought was my problem for some time).
Which seems like a problem. If the until has to run for too long, then the water fills up and then the inducer motor stops.
Does this seem like it is working right? Or should it drain the entire time?
Thanks,
Anthony

It sounds like your trap may not have enough height to keep air from being pulled in. I have to make traps that were close to 5" to prevent the pressure from pulling the water out of the trap. Yes they do get dirty and need to be cleaned, but if the trap is holding water it will drain while running, if the trap is not deep enough air is pulled through the trap and water will build up until it is deep enough in the pan or shuts down and gravity pulls it out.
