Roof Fan

[Husty]

my roof fan runs continually. I followed you repair procedure and found that the 4 wire connector from the roof fan is not connected to anything at the furnace. I do not find a lower control box. where do I start? I purchased the mobile home in March of this year.

Do you have a Coleman Furnace with Blend Air system or a Miller/Intertherm with VentilAire system ?



Thanks,
Robert

The mobile home is now closed for the winter. I am going to find out the information that you require. Thank you for your quick response

Hi,

Sounds like there are missing components, you'll need to determine what is missing.


It may not be repairable. You may be better off replacing the system.

You could replace missing parts only to find the others don't work.




Thanks,
Robert

Robert,
Where could I find the parts list and system description?
I think a this point I need a service manual or all of the specs for the system.
Thanks again for your help.
