Good morning! What are we working on here? Make and model number?
Oh, OK, this is related to electric heating element. I'm going to open this up to other experts. Please do not reply or the question will come back to me.
The elements do not become oxidized causing poor or no heat. Do you have either a mutli meter or an amp meter for troubleshooting?
Is this heat kit installed in a Carrier Air handler? If so do you see a model on front of unit with an F in model, like a FA4C or FC4D or similar?
That is the actual heat kit model. Is it in a ducted air handler or some other unit like a mini split?
Ok there should be a label on outside panel with a Model like mentioned above if it is Carrier.
What is concerning me is the low amp draw 9000 watts divided by 209 volts = 43.06 amps.
Ate 209 volts we should be getting 14.35,28.7 and 43.6
Will you have internet access when there?
If you have internet we can do that and come back to question while there would be great.We may have something in there creating a resistance on the elements or something.Then we can do a temperature rise check.
Normally the dust would burn off within a few minutes
If all elements are coming on but temp rise is low, we may also need to slow her blower down to a lower speed 9KW is not a lot of heat so if air is moving too fast across coils we end up with insufficient temp rise.
Sounds good, We will go from here.
