Help with Lennox Code.

I have had the Lennox Furnace G71MPP furnace and heat pump installed for 3 years. Every year when the temperature drops below the heat pump minimum setting the furnace heating will not start. We had an error code A350. Turned off and back on the furnace and now have error code A622 and H70 which I connot find in the manual. We have no heat and a Saturday having difficulty raising a service rep. Please help.

I am not up on these codes w/ Lennox.

From what I can make out on page 25 of the manual, A=Fan speed. H=heat stage. So your fan was running 622 cfm, and your heat stage is at 70%..

I am going to move you over to the gas heating section, and someone there may be able to help.

That is a very high end furnace. I recommend a pro. It should have a 10 yr part warranty.

Unfortunately, your furnace is smarter than most of the people repairing them...
