SOURCE: I have a Goodman GMP075-3. Worked OK on A/C.

I come across this one a lot. You need to switch the wires at power cord.

  1. Pull power out
  2. follow the cord* back to the furnace
  3. Open the front door
  4. There should be a small metal box where the cord leads to inside the furnace
  5. Open that up
  6. Take the electrical tape off
  7. Pay attention to which wire goes where
  8. Switch the two wires around

My goodman GMVC95 furnace circuit board is flashing On 6 I replaced the flame sensor but it's still flashing. Does it have to be manually reset?


Alright, have you checked the low voltage fuse on the circuit board in the blower compartment? Make sure you check the roll out switches as well. If all of these issue appear to be fine then you may have a bad circuit board. There has been a bad batch of circuit boards going around many of the popular furnace brands this winter. Trane Gas Furnaces and Goodman Gas Furnaces have been effected. We sell both brands and have had to replace many circuit boards on new furnaces.

Goodman GSC130421ab has no voltage to contact after washing coils....it worked just before powering off unit at diconnect to clean the condenser coils


very posisble.check the fuse on the board on the indor unit. replace with equal size fuse (not bigger probably 3 amp). if the indoor unit comes on then the fuse is fine and i would suspect the coil on the contactor has shorted

I have a Goodman heat pump and the condenser fan and compressor will not switch on. The board green light says improperly grounded or flame sensor not sensing flame (both are incorrect). The AUX heat (gas)...


Does the indoor fan run? Place the fan switch in run. If it doesn't run then the transformer could be bad. Also, there could possibly be some high and low pressure switches that would keep you from getting the 24vac to the contactor. First rule out the thermostat by removing the face and installing a jumper wire between the R and Y terminals. This should make the outside unit run. If it does then your thermostat is not passing 24vac to the unit and should be replaced. If it doesn't run with the jumper in, then your problem is in the outside unit. Trace out the yellow wire from the thermostat in the outside unit and check the components that the wire goes through (high and low pressure switches). Let me know what you find so I can offer more help if needed.

Goodman a/c blower fan will not shut off


Unhook the thermostat wires on the furnace. If the blower shuts off then your problem is either the thermostat or the thermostat wires. If it contiues to run check you high limit switches next. If all else fails you most likely have a bad blower relay. On most modern furnaces the blower relay is part of the circuit board.
Good luck
