It is VERY level.
No yellowish residue.
It don't work on AC or LP.
Was working fine 2 months ago.
I turned the switch on the day b4 yesterday overnight and the green light stayed lit like it should but never got cold. Then I switched it back and forth and now it flashes the 5 time thing.
I checked the roof vent and it is all clear.
Trying on AC, the green light flashes 5 times every 3 seconds.
On LP, the orange light is on and the green light flashes 5 times every 3 seconds.
I already did what the service manual said to do and that didn't reset it either.
