I have an old Intertherm electric furnace model: MAC 2454A. It will not stop running. Two years ago the heating element would turn off but the fan kept running at which time I installed a new sequencer and that fixed the problem. Now neither the heater element nor the fan will stop running. I have disconnected the thermostat which made no difference. Any ideas to what might be causing this?
