Hi All,

I am new in this forum. can anybody suggest me how to reset AL22 on 69NT20/40? My understanding is Alarm 22 responds to the evaporator motor internal protectors.

Hi Mohsin!

I think the alarm can be cleared by running a "pretrip" on the unit. But i suggest checking the fans because of the overheating alarm, bearings, wiring, windings...
