The only sure way is to connect a good motor and see if it runs. In the last year I have replaced a few of those motors and no control boards. All the tests are electrical and the normal failure for that motor is mechanical.

Dryer runs but no heat


Hi jmacc_jaffha
I am also including a link for parts and breakdown/schematic of your dryer.
Here are a few things to check:
ALWAYS UNPLUG YOUR DRYER BEFORE ATTEMPTING TO DO ANY WORK ON IT.
Check to make sure you are getting full 220 Volt power to the dryer, if you are then:
Check your Wiring
Often the main wiring connection from the house, at the dryer, burns and the connection breaks. If this has happened to your dryer, you need to replace the power cord and the terminal block inside the dryer to which the wire is attached.
Check the Door Switch
If the door switch or the door-switch actuator is defective, the dryer won't work and you need to replace the failed component. The switch is inside the dryer main housing near the door frame. Sometimes you need to raise or open the top or front of the dryer to reach the switch. Check for continuity you should have none with door open, and should have a reading when closed. If not replace the door switch.
Check to make sure you heating problem is not a lint build up in the discharge hose or inside of the dryer venting system,as this condition can cause heater/thermistor problems such as overheating of the heating coil leading to failure of the coil and burnout of the heating element/thermostat/thermistor due to overheat.
Remove the back/or front just under the door of the machine and try to locate the air duct going from the blower to the drum. Normally inside/outside the air duct you will find the heating coil and the thermostats/thermistors. Once you have located the heating coil, remove the two wires from it and check the coil with an ohm meter across the two terminals of the coil.
You should read continuity across the terminals, if you do not read continuity you will need to replace the coil as it is faulty.
If the heating coil is ok, then:
You can check the thermostat/thermistor/thermal fuse one at a time by removing the two wires and taping them together with electrical tape.
Try to run the dryer, if it runs and heats up then replace the thermal fuse/thermistor/thermostat.
If you have an ohm meter then you can test the thermostat/thermistor/thermal fuse,then you do not have to tape the wires together as described above.
But do not trust the ohm meter all the time, because sometimes it will give a false positive that the fuse is ok when in reality it is faulty.
DO THE FOLLOWING TEST:
To test your thermostat/thermistor/thermal fuse remove the wires from the thermostat/thermistor/thermal fuse and check the fuse/thermostat,thermistor for continuity, if you DO NOT have continuity then replace the thermostat/thermistor/thermal fuse.
DO NOT LEAVE THE WIRES TAPED TOGETHER AFTER THE TEST AS THIS COULD CAUSE A FIRE BECAUSE YOU HAVE REMOVED THE SAFETY.
This test of the thermal fuses,thermistor,thermostat, will show if the thermal fuse,thermostat,thermister is really faulty or not.
Check your blower wheel to make sure it is secure to the shaft and not plugged with lint,socks,etc. If you have to replace your blower wheel it will remove clockwise as looking at the blower wheel. You will have to hold the belt end of the motor with a vise grip pliers or maybe the shaft of the motor has a notch cut on it for a wrench to fit.
If the thermal fuse overheats the dryer will not operate. It's located on the blower housing. It cannot be reset.
You can test it with an Ohm meter or continuity checker, remove both wires from the thermal fuse and put the test probes to each of the ends of the thermal fuse, if no continuity then replace the thermal fuse.
If you do not have a volt/ohm meter then:
DO THE FOLLOWING: Remove the wires and tape them together and try to start the dryer.If the dryer starts then replace the fuse.
A vent clogged with lint can cause it to overheat.
Right after replacing a dryer element, always run the dryer on air fluff/no heat, and go outside to verify there's plenty of air coming out your vent system.
If the vent's clogged, that new element can burn out very quickly.

Timer ticking and heating element activating when dryer is off


One thing to check is if the heater is shorted to frame.Remove the wires and do the checking. If that is fine then the only way the heat can come on at all is IF the motor is running. So check between terminals one and 2 for continuity with the motor NOT running. If you get a reading then your motors cent switch is stuck. You can sometimes oil the springloaded sliding switch but most times the springs have broke on it.

Hi.

More than limit switches if burner is turning on but heating is poor you should check cycling themostat and then blower motor, lint filter and parts comprised in blower assembly.

When the problem is the high limit, there is no heat at all.
When the problem is radiant sensor, there is no heat at all.

Poor heating means either: defective cycling thermostat; clogged air ducts; defective blower system, problem with timer or temperature selector.

If the heating turns off in the middle of the cycle check also door switch.

Here Cycling thermostat:


10_22_2011_10_57_23_am.gif

The cycling thermostat is located in the blower assembly. Here removal instructions. Disconnect power first:

10_22_2011_11_00_07_am.gif

The thermostat can be tested using a multimeter. Set the multimeter on impedance (Ohms). Good thermostat will read about Ohms at room and will read open (infinity) at 150F.

Once in there also check the thermal fuse and check blower assembly. Remove lint and make sure blower is working. Thermal fuse is tested reading impedance across its two contacts. Remove fuse from circuit and touch with multimeter probes fuse's contacts (same for thermostat). If fuse is good it will read zero Ohms or very little impedance. a bad fuse reads infinity.

Check also the exhaust. Make sure there is no blockage.

Operations are illustrated from page 72 of service manual: Here the service manual.


10_22_2011_11_09_36_am.gif

About the flame sensor, that is a part that rarely fails. If the dryer ignites the radiant sensor is not responsible for the fault.
The radiant sensor is mounted in parallel with the coil.



When temperature is reached the sensor opens up allowing power to burner valve (valve 2). Testing the flame sensor like a thermostat is difficult because it opens up at high temp. I read volts while operating. I suggest users carrying only maintenance that can be performed with power off.

10_22_2011_11_18_01_am.gif

If the burner shuts down at random more than the sensor check the door switch. Run a cycle with door switch contacts jumped.

Start checking cycling thermostat and air ducts, those are problems that usually cause low heating.

Regards.

It could be possibly your rear roller bearings expanding with heat causing them to not spin as freely? Im not really too sure but its an idea you dont have many moving parts on the unit. Just your idler pulley, blower wheel, and rollers. Hope this helps.

My Dryer Maytag PYE2300AYW is dead


HI. A blown fuse will show no continuity when measured with a meter. Before replacing the fuse, make sure the blower wheel is not broken or clogged, and there is nothing blocking the venting.

Concerning the Control Thermostat(53-2880). This is the main control thermostat. if it is covered in lint as you have sated, this will confirm thermostat failure. this has tripped the thermal fuse in this case, totally rendering the dryer inoperable at this time. you will need to replace the Control thermostat and thermal fuse as well. this will fix your unit.

The thermal fuse can be tested be using a basic voltage needle but, it is really not needed. the thermostat has failed. the over cover of lint has shorted the device(lint will create an arch that will ruin the device)

Once the thermostat failed, the heat will rise to a unacceptable rate and, this will trip the thermal fuse and kill the dryer. its a safety feature to prevent a fire in your home.

Hello, If I am reading this correctly you have an electric dryer with no heat..you have checked oll the usual suspects like heater coil, breaker, thermal fuse the all look good..you dont have condinuity on the running thermostat...there should be 2 large wires going into this..and 2 small wires..the 2 small ones will show no condinuity..the 2 large wires will...so if your 2 large are not showing condinuity change this part...if they check out good it's going to be the centrifigal switch on the motor...this switch is built into the motor and will only alow the heater to activate if the drum is turning...you can test this by bypassing the 2 big wires going into the motor..if the heater goes on you know the switch is bad....unfortunatly it is built into the motor which is going to mean a new motor...hope this helps...if you have any other questions please feel free to comment again...good luck!

Blower doesn't blow and no heat


With these GE Harmony Profiles, the blower is the problem in same situations about 95% of the time.

First use the dryers service mode and see what trouble code you are receiving.

It's called "Field Service Mode"
1. Press the POWER key to turn the dryer on.
2. Press HELP. The main help screen is displayed.
3. Press and hold MY CYCLES and BACK simultaneously for 3 seconds. Press EXIT to return to the HOME screen.

There's a 95% chance that it is your blower and your dryer should confirm that.

I just recently replaced the blower in my GE Profile Harmony as well. While I had my dryer apart, I also cleaned the heck out of it. Excellent opportunity to take your vaccum cleaner and get all of those dust bunnies out!

I purchased the blower from www.applicancepartpros.com for about $146 S&H included.
