On the heating element [behind the coil, (the springy thing)], at the top end of the element, there is a little thermistor I think it is called. You will have to remove the fan shroud. With the power off, check for continuity if you have a multimeter. If that is the problem (no continuity), you can pick one up at al local heating supply. Just have it soldered back in and reconnect. If the thermistor 's continuity is okay, remove the main board under the control knobs. I have seen these boards burn in the back where the relays are soldered on. If you're really good with a solder you can try to re-solder it. If not, it's about as cheap to buy a new unit as it is to buy the board. Good luck.

99% of the time proves to be a short- in the thermostat, furnace, condenser, or the 24V wires between them. Time to get out an ohm meter and check continuity between the wires and between each wire and ground - detective work - can be fun!?
Much less likely: condenser contactor, furnace control board, other condenser controls any of which could be drawing too much current. I bet on a short curcuit but if not I'd try changing the contactor first I think.

Check the O/B setting on the thermostat and equipment to insure the reversing valve is energized during the proper heat/ cool cycle. Also check the thermostat wireing to insure electric heat element is set up.

Could be a lot of things. About the only thing you can do besides calling a service tech is to 'make sure your coil on the condenser (outside) is clean. This coil can be cleaned with a water hose, but you need to make sure you have all electricity turned off.
Turn off the breaker on the outside unit (this could be a fuse block that you have to pull out) and make sure you have your inside thermostat in the off position.
Once you are 'absolutely sure' that you have all electricity off - you can wash the coil with a high pressure hose. Just make sure that both - the inside and outside of the coil is clean; you may have to disassemble the unit a little bit, i.e. take the top off or one of the sides, etc.
The only hope you have - is that the coil is clogged and causing the compressor to overheat and go off on amp overload. It's possible this is the case - but I also suspect the compressor is electrically breaking down which is not connected to the condenser coil being dirty, in which case you will need a service tech and may be faced with some expensive repair. Let's hope this is not the case.
So - it's worth a shot to wash the outside coil.
Not to be 100% negative - it's possible it's something minor and when a service tech looks at it - it could be a fairly cheap repair bill.
Good Luck!

do you have an automatic change over thermostat? this would switch it from heating to cooling.
