I have replace the heating element,which had a broken coil.Also replace dryer cycling thermostat,dryer thermal fuse and dryer thermal cut-off-kit.I clean out dryer throughout. dryer has been working great for the last three weeks but now is tripping my circuit breakers after running for about 15 minutes,I check to see if unit is hot or overheating but no,I also check to see if circuit breaker is hot but no. Please let me know if you could give me some advise. Thank You model#TEDS740PQ1

make sure you have proper airflow for heat, clean lint trap and good ventilation and check the outlet, test to see if your getting 240v

I cannot find any info on the given model number. Please check it. Are you sure it that the "e" is not a 0.
This may be difficult to troubleshoot. If you can get hold of a clip on amp-meter, then you could monitor the current to the unit. Then if you see a a current spike just before the breaker trips, you know that something is heating up in the unit and then shorting out. Also it will let you see what the current draw is.
I would check the heating coil. Unplug the unit and both wires at the heater. Measure it, it should be 8 to 12 ohms. Then measure from each heater connector to the frame/ground, both should be infinite resistance. My thinking here is that the heating coil has grounded out in such a way that it still heats up but is shorting to the frame and drawing too much current.
Could also be that the breaker is toast.
When it blows the breaker can you reset the breaker and the unit will start right away. If you have to wait a while it could be a problem with the motor overheating and tripping it's in thermal thermal cut-off. This is a long shot as the motor is not only overheating but also shorting out when it overheats. |

[COLOR="Blue"]I had this breaker installed new with a baseboard heater on the same line,could this be a problem if they are running at the same time[/COLOR] Yes it could you may be pulling too much current. Below is an install sheet. https://www.whirlpool.com/digitalassets/MLPDF/Installation%20Instructions%20-%208577187.pdfSince I could not find anything for a TEDS74ePQ1, it is for a TEDS740PQ1. It calls for a 30 amp dedicated line. Lets say that the heater is 10 ohms this will then pull 24 amps, then on top of this you have the amperage required to run the motor so you do not have many amps left. Turn the baseboard heater off and see what happens. |

Mr Denman I want to thank you for your assistance, and seing that you are a senior expert appliance technician give me comfort,but most of all I admired that you are a volunteer, Thank you and as soon as I go through the pointers you gave me I will let you know.David A
