Actually, it does run for a split second then shuts off with PF (Power Failure) on the display. I've taken the unit apart, cleaned everything, the vent is only 3' long and goes directly outside. The model # is gleq2152eso, I've retrieved code(s) but E9E is the prevailing one I'd say and isn't on the TS list. I've done my reading and everything points toward the thermistor which reads 45.6 ohms, wires to the panel or the panel itself...the wiring looks good going to the panel. I'm hoping that there's some other issue that I can check. Partly due to the panels cost of $177 and the fact that it's out of stock on the Repair Clinic site!
