    This just happened to me early Thanksgiving morning- almost set the house on fire. I caught it just in time. Why did this happen and what is Aprilaire doing about it?

    How many times must one fix something before it is fixed?

    Yes I changed the canister at the end of March. I have had the unit for 6 years and maintained it diligently every season. I live in Denver Colorado so humidity is important.

    Good, and was it checked for proper operation each time. Amp draw and production rate.

    I keep the front cover off and a watch to make sure it producing steam. With a 220V setup it doesn't take long. I then can monitor the steam production by looking at the Humidity level on the thermostat.
    The real question here is why did this happen and what is Aprilaire doing about it. It SHOULD NEVER CATCH ON FIRE!!!!

    We are not Aprilaire and can not answer your question. You may want to contact them directly. No, it shouldn't catch on fire. Maybe call in a local contractor to analyze it.

    Its not a common occurrence, so eliminating errors or neglect is the first step. Next, have you even contacted Aprilaire about this.

    Yes I have contacted them- they wanted to see the pictures, which I have sent. And Yes I know you are not Aprilaire, but this community should know that there is a problem here.
    I had my local HVAC technician inspect the adjacent systems- Heater and AIR conditioner or any colleterial damage. He said he had installed hundreds of these systems and never saw anything like this.
    If this happen to you- you would be upset too.

    Its not a common thing. With you, only twice is anything on this board about it, and as you saw, the other one was 5 years ago.

    So wait until Aprilaire gets back to you.

    Sorry but we can't help that you are upset and admittedly I would be also. But, think about what your HVAC guys said... he had installed hundreds.

    There must have been a wire short of some sort for this type of heat. Could have been any of your home 240v connection. Remember you said it doesn't take long for it to create steam? Think how long a resistance short would take to heat up. Actually... a heating element is two legs of power with resistance in between the two legs... a loose wire connection from your home power could create this mess.

    I and we hope you find your answer, truly, but not sure how we can help. Good that you are talking to AA direct.

    I'm sure bypassing the safety switch won't help your case. the unit is not supposed to run with out the cover on. can't imagine how that would affect it.

    My wife has one in her Yoga studio, works like a dream, probably a loose wiring connection. I have never seen anything like that, I have been selling Aprilaire for 40 years.

    X2.

    That also looks like 14/2 Romex. The installation manual calls for a 20 amp breaker for the 11.5A setting and a 25 amp breaker for the 16.0A setting. That would require number 12 copper wire for the 20 Amp breaker and likely number 10 copper wire for the 25 amp breaker.

    Looks like there are some installation errors in the picture.

    Edit...ok just realized OP is posting pictures of a unit that is not his as well as his unit.

    Second set of photos has the LV wire running in the same connector and KO as the high voltage. Big no no and sloppy. Wonder what other corners were cut.

    How many faulty brakes did car manufacturers have before they did anything?
