GE DPSB620EC1WW Will not turn on Heating Elements

I have a GE Profile Series Dryer that the heating elements will not turn on. New control board from GE did not fix the problem. 220 vac present at K2 & K3 on control board. Elements check out ok and centrifugal switches are ok and elements are ok, but control board will not turn on K2 or K3. Could I possibly have a bad Inlet or Outlet thermistor?

    As I stated in my posting, 220 vac present at K2 & K3 on Power Board. Elements are good and motor switches are good back to second leg of 220 vac. Something is telling Power Board not to turn on the elements. If I knew what the values of the Input/Output thermistors are suppose to be that would be a great help.

    Hi and thank you for the reply!

    Now we are getting somewhere. The Inlet thermistor (white wires) is reading 103K ohm and the Outlet thermistor (blue wires) is reading 7.3K ohm at room temperature. I am guessing the Inlet thermistor is so far out of range that the Power Board doesn't know what to do with it, so it does nothing. Sound like I am on the right track? Dan

    Well, based on the information you provided, I went and purchased a new Intake thermistor. The new thermistor reads 96k ohms, not too far from the one I thought was bad, which reads 107k ohms. I thought the thermistor values you gave me were for both Input & Output. What gives? I now think I have a part I don't need. Do you have any other advice?

Yes... that is very possible... If they didn't fix your problem i'd complain if i were you... but there might be an issue with your motherboard... you should check to make sure the wiring and circuits aren't defective. i would suggest you reset your dryer... comment me if i didn't answer your question.. thanks

    Yes, you are on the right track. The thermistor is bad.Once you fix this, probably it would fix the issue.

I switched off the power prior to looking at this, i did not wire it. landlord replaced thermostat yesterday after the heating element had already been replaced2xs now, 0 hot. heater model 71-40sb

Is this a 220 VAC H/W Heater or a 120 VAC H/W Heater?
Note: Info provided here is for a 220VAC H/W Heater
Thermostat doesn't look like a new one, maybe it is used!
Check input power (voltage) on top two wires if this is a 220VAC H/W Heater ... then the input power from the C/B in the Electrical Panel should be 220 VAC. If 220 VAC power is not present on the top two wires ... you may have a bad C/B in Electrical panel. Make sure C/B is turned ON and if still no power on top two wires replace C/B. If 220 VAC is present on top two wires then press Red Reset Button very hard to make sure it is Reset. Then check for 220 VAC at the Thermostat ( bottom two terminals), if 220 VAC is present then check for 220 VAC on the Heating Element terminals (bottom of picture). If 220 VAC is present on the terminals of Heating Element then H/W Heater should be working otherwise Heating Element is Bad and replacement is necessary. Good Luck! Handy Henry

Cannot get the top part of my double oven to heat nor broil. The oven model is JKP26GOP2BG GE appliance. I have check voltage going to the oven and it 240 VAC and ohm the elements and they checked fine. ...

the thermal control has failed

check here
perhaps as you get 126vAC ?? strange its half the supply volts
perhaps a missing something
i think your elements are in series or a missing nutral ???
each will measure 126 this way
you can atleast check the sensors resistance

mesure from nutral at the mains to each element point
did you disconnect the elements then test there resistance

even getting 126v they will heat .. half up....

so something isnt right
hope i can help

When you installed the control board was it part number WB27T10305? The reason I ask is because the problem that you are describing sounds like a stuck relay on the main control board, the part number listed above

My dryer is running, but doesn't have heat.

All electric dryers use 220-240 volts of electricity to run. The elements that make the heat are what actually need the 220 volts, the motor that turns the drum only uses 110. If you have a fused service disconnect box, replace both fuses, as one side is gone. 220/240 is made up of two 110/120 lines coming in, if one fuse, one side, blows, then all that's left is the 110/120 needed to run the drum motor, but no 220/240 to run the heat element. If there is no service disconnect then check the breaker than runs the dryer, flip it off and then back on to see if that makes any difference. Sometimes it will. Then there's the possibility that the hi-limit thermostat on the heat chamber in the machine blew, letting the drum run, but not feeding the coils. If you're not real handy with tools you may want to call a repair tech for this one.

Remove 1 wire from the element . Your 220 V comes from ...110 motor , 110 control board . Check which wire is not getting 110 V , trace it and see which it comes from . That will tell you which one is defective .

MY drier heating element shows 9 ohms continuity, it also shows 120 volts into and out of it when the drier is running. But the heating element wont heat up?

Have you checked the voltage at the outlet? You're supposed to read 220-240 VAC at the heating element. Your dryer heating circuits require at least 220 VAC to work. The motor, however, only uses 120 VAC. That's why your dryer may be running, but the heating circuits aren't heating. I would go back and check your outlet. You may be missing one leg of the 220 service, or have a loose, burned, or broken wire in the plug or terminal block (on the back of the dryer). Let me know what you find. I hope this helps you.

Dryer Doe Not Heat

Have you got both breakers working? Turn them off and then on. Is the timer or relay board doing its thing? What about the thermostat? Follow the diagram on the back of the unit with a multitester. Be aware of the fact that 220 V can kill.
