Heater will not shut off runns continously, have to flip breaker
My heater and central air when turned on will run continously the only way I can get them to turn of is flipping the breaker. I have change the thermostat out two times, and installed a new control board. Any other things I might try?

Re: Heater will not shut off runns continously, have to...
Maybe youhave a pinched thermostat wire. If the room air blower is blowing, At the control board remove the wire located on the G terminal. What keeps this blower turning is a connection between the R and G terminals. The heat is caused by a connection between the R and W terminals. So if you disconnect the R wire and the unit turns off, you do have a short in the thermostat wire. If it keeps going, you have a bad board.

check batteries in thermostat? you'll need a voltage tester,either neon light or vom.check to see if breaker is tripped.throw back and forth if it looks ok.remove cover check to see if power is getting to breaker then out of breaker.The heat is turned on with a low voltage circuit. check to see if you have 24 volts coming out of transformer.if all this checks out it gets real tricky. power to heating elements is switched via switches that are back a ways amongst lots of wires.very dangerous to work on with power on.I don't recommend trying to go further.
If you flip the fan to on and it doesn't run then you may have a problem with the fan motor or possibly a capacitor if it has one. I'm not familiar with the Brant heaters. I usually work on Monitor and Toyostove heaters.
No the humidifier is okay the problem is the element inside the heater. It is drawing too many amps and needs to be replaced. I can go into the reason I say that but would be talking about resistance and electrical circuits. Which gets real boring real quick. Just had the same problem couple weeks ago so it is real fresh in my mind. let me know if you need any more help. That electrical element just pulls out of cabinet and then get a new element kinda like a clothes drier element. Don't touch the element with your fingers use some gloves to install.
You don't mention make or model so here is my guess as to how to thinkout the trouble of what ever is in your attic.
For some reason, your heater is mis-firing. Normally, I would expect 3 to 5 such events at which time the heater goes out on safety. The heater knows it is on safety but you don't until it gets cold in your house. When you turn the power off, wait the 30 seconds, turn it back on, the heater no longer knows it is on safety (memory cleared) so it fires. Your heater continues to fire until ? at which time it starts counting again to 3 or some number. At the max mis-fire number - it goes out on safety again ... repeat - turn it off, wait 30 seconds, turn it back on - no memory and so forth.
Do you have a service contract or regular service man? Might be time to find one.
Sounds like it may have lost power. Check the breaker and the fuse at the furnace. If they are all in the on position and working then it sounds like you may need a technician. If the display is blank on the thermostat you may also want to replace the batteries.
