I had an Aprilaire 5000 installed over a year ago. I have had the contractor who installed it back twice.
First the light stayed on all of the time (after blower shut off). They came back and it worked for several months.
Next the light would not come on at all. They replaced the door. It worked for several months.
Now the light is staying on all of the time again.
I would not mind paying to get this resolved but have lost confidence in this contractor. Any suggestions?
