Intertherm electric furnace will not stop running


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?

Thanks

Thanks all. Diagnosis seems to be unanimous, and as it turns out, correct as well. I removed the sequencer that I had installed just the winter before last and it tested bad. Replaced it with a new one and the problem is solved.
