    Intertherm Funace diagnostics code
    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.

    Look on the blower door at the wiring diagram. It has a code for the number of flashes. On a mobile home unit it might be located elsewhere on the unit. Try to find it if possible,
