    Intertherm furnace troubleshooting
    My intertherm #e2eb-01sha electric furnace mostly just blows cold air. Sometimes however the heat works just fine. Also, anytime the blower is not running the furnace is hot so we have to turn off the safety disconnect. We have tried replacing the thermostat to no avail. Help please Michael

    It is possible you have a defective sequencer. This item also can control when the blower comes on and off in the heat mode. Unless you have a electric meter and know how to use it you will not be able to test the sequencer and its operation. Also I show NO Intertherm furnace with that exact model number.
