    Got the problem fixed. Was the furnace unit, not heat pump. Pressure switch was stuck.

    Thanks

    Need more information, is the unit a heat pump, is the board on the fan unit or the out door unit? Is this a split system or a package system (all in one outdoors)?

Removed the flex hoses from the pressure sensors and reinstalled them. Unit reset and now works perfectly.

I would try to check your return air first, making sure there is no blockage and that your air filters are clean. It almost sounds like when you take the cover off, you are pulling enough air into the system for it to run, but as soon as you close it off, it's not getting enough air flow, therefore, tripping a limit switch inside the furnace. Most furnaces will also have the codes for the flashing lights and what they mean on the inside of the door covers.

sounds like you have bad flame sensor or the sensor is in a bad postition. To get eliminate the lockout turn the power off to the unit and back on again. Look at the circuit board light and see what the troubleshooting code is.

does the furnace ignite?? your system may not have been lighting and has gone into ignition lockout count the codes of the led lights then remove panel led diagnostic codes are listed there.

4 blinks is "pressure switch closed" there are 2 in the system according to the wiring diagram one for the vent system  and one for the drain system ... I just wiggled them and heard one "click" the fault light quit blinking and when I pushed the safety switch back in the furnace fired right up.  That being said is there a good website for learning how to maintain your own furnace?  I'll call a pro if I have to, but shoot I can fix a jet engine... this shouldn't be much worse.
Thanks  dan
