I have an Intertherm Furnace in a mobile home that I own and rent out. The furnace has a self diagnostic capability and shuts down periondically. The indicator lamp(red light) flashes in a series of four (4) flashes after it has shut down. I can reset it very easily by turning off and back on the power. It will run for several days and then do the same thing. I have already changed the filter to a free flow filter. My Question is what does the 4 flashes indicate? Thank you in advance.


I have looked all over for this information and cannot find it any where on or inside any furnace component. Thanks again.

Post your question here under Nordyne. These folks have a great board for mobile home furnaces and they also have the parts available if you need them.
