I have an Amana furnace with a 50m56u-843 control panel. Air conditioner was working fine, but when put into heat mode, the panel blinks six times, meaning that there is a problem with roll-out switch. Bypassed the switch, same problem. Do not know how to reset the control panel, so I put in a new one. Once again, the air conditioner worked perfectly, but I was stupid and tried to put the heat on. Now the system is locked up again, the air conditioner will not come on and the error code of six blinks is back. I disconnected and reconnected all the wires, but the panel is stuck with that error code again and nothing will run. What could the problem be? Any help would be greatly appreciated.
