Our electric furnace has been acting strangely and I suspect it's a bad sequencer. It will run and run and not shut off (came home yesterday and it was 86 degrees F in the house). I shut it off and now it seems to be operating normally, though it seems to be running more often than it should. When the furnace is not running I put a volt meter across the heater coil terminals and I'm reading 240v on the number 3 & 4 elements, 0v on numbers 1 & 2. I'm thinking that if it's not running there should be 0 across the elements.
