Is/was your air filter dirty/plugged?

Might be off on its high limit. When was the last time you changed/cleaned your air filter.

The high limit is to be closed when ever the temp is senses is below its trip point.
It only opens when the air temp is TOO hot.

An ohm meter will tell you if its open or closed.


How dirty was your old air filter you just changed out?
