Installed a 700 to a Lennox pulse furnace. It worked two weeks and is now dead. During it's working time, the unit would engage at the same time as the furnace fan wether the furnace was burning or not. Basically a lot of on off's. The light indicators on the control are both out. No activity at test mode with furnace running. I like to keep things simple. If a suggestion to replace the Auto trac humidity control: Would a 4016 low tech work or another Auto trac. Is there anyway to test which component is not working?
Thanks in advance
