If you recently put in new thermostat make sure you
put the wires back where you took them off. Turn
unit off,remove blower compartment door. Find where
thermostat wires connect to board, G-terminal is usually the control wire for the fan. W1 or W2 terminals are usually resevered for the heat leg. Disconnect them both, put those wires out of the way, Put door back on and turn power back on
nothing should be operating. Turn power off

Remove thermostat and find what color wires go to
W1 or W2 and G. Put thermostat back together,
go to the indoor unit where you were before,

Whatever color wire you had at thermostat W1 or W2
connect on the control board to W1 or W2. Do the samething for the g terminal or what is called the
fan leg.

Good Luck

Check for power to the unit. If power exists, check your low voltage. Do you have 24volts to R & C at your thermostat?

Heating Element A defective heating element can make a dryer too hot. If the element partially shorts out, it can produce heat all the time, regardless of whether the dryer is calling for heat. Remove the heating element to inspect it. The coils should not be touching each other or anything else.

Heating Element Assembly A defective heating element assembly can make a dryer too hot. If the element partially shorts out, it can produce heat all the time, regardless of whether the dryer is calling for heat. Remove the heating element assembly to inspect it. The coils should not be touching each other or anything else.

Air Flow Problem Dryers need good ventilation to work properly. If the vent is clogged it can make the dryer too hot. Clean all of the vent tubing thoroughly.
Cycling Thermostat Although not common, a defective cycling thermostat can make the dryer too hot. The cycling thermostat is supposed to turn on and off the heat to maintain the proper temperature. If the thermostat is defective it may keep the heat on too long. The thermostat is not adjustable or repairable, it must be replaced.

Felt Seal Most dryers have a felt seal at the front and rear of the drum to keep the heat inside the drum. If the felt seal is worn away or missing, the dryer may keep heating and make the dryer too hot. This is not common.

Blower Wheel A defective blower wheel will not spin properly and will not vent the hot air, making the dryer too hot. Check to see if there is adequate airflow out of the dryer.

Finding Pilot light on Goodman Model caf024a2a. Cannot seem to find the pilot light...The blower works but no heat.


i think the ca # is for the cooling coil unit - the heater should start with gmXXXXX - if your unit is fairly new - the pilot light electronically when thermostat calls for heat the unit will not light if the burner door is open

NO HEAT


A blower relay usually has a set of closed contacts that go to the  motor and when the 1st element comes on the power goes on through the sequencer and then these contacts and to the motor heating speed. If you have a blower in AC and with the fan sw to ON u can run the blower on manual 100% of the time until someone can come look at it and the heater coils will cycle on and off with the thermostat. Dont worry about the cost compaird to the elements the motor is nothing and the heat it generates is going into the heated home anyway.
