Maytag Electric dryer

Dryer Repair
1

Dry runs but does not heat. No obstruction. Had broken wire from one of the heating coil. Repaired, still no heat.
Presume that a fuse is blown but find none.

Hi,

Check to make sure you have 240 volts to the dryer.

Thank you. We have been having some problems with brown outs recently. The circuit breaker is not tripped. However, I will check the voltage this afternoon and get back to you.

Voltage tests at 120 on each side of the terminal on back of the unit. Using the common in the middle, I tested each side and got the same reading on each.
Thank You

There is a thermo fuse on the heating element and the blower housing.

You can check them with a ohm meter. They should be closed (shorted) if the are ok.

If one is open (like a bad fuse) then replace it.

If you find a bad one you can jump the two wires out just for testing to see if it heats.

There are three thermal fuses on the unit. Two on the blower cover and one on the heating unit.The two on the blower housing have three tabs. The 2 outside tabs show continuity on each. No continuity on the third tab. It seems to connect the two fuses.
The Thermal fuse on the heating unit has two tabs and it shows continuity.

Each shows continuit to the one on the heating uint and the upper connection to the heating element. Testing the heating element shows continuity between both terminals.

Still no heat.

Thank you

Then you need to check for 240 volts at the heater when it is running.

If you have voltage there, then something is not yet right with the heating element.

If you do not have voltage you will have to trace it back to were you do.

Thank you
Can I test this by checking voltage across both ends of the heater element while the unit is running? I suspect the main black wire attached to one of the heater coil posts. It comes from behind the drum. It may have pulled out. on the far end. Does it come from the timer switch in the header panel? Initially this wire was broke and I repaired it. I may have pulled it too hard for access for the repair.

I tested across the heater coil posts with the unit running and found that I had no voltage at the coil. I will trace the main wire back to see where it is failing.
Thanks

I have continuity from the timer switch to the heater coil tracing the black wire. I also have continuity from the black wire on the power block to the heater panel.
Could it be the timer?
Thank you

any other suggestions?

I would check the terminal block on the back of the dryer (were the power cord is connected to the dryer) for burned wires. Also it should be 240V between two hot wires besides 120V between each hot to Neutral. Make sure you have 240V.

I have 240 total at terminal block

You said there is no 240V to the heater. I would recommend to check the power separate between each wire (wires should be disconnected from the heater) and the ground. Probably you’ll find a 120V on the one wire and nothing on the another. Trace the wire with no power and see were it’s going. The problem is some were there and it could be the timer too but I do not want you to waist money. Let me know your findings.
Be very careful working under the power!
Good luck.
Gene.

Thank You
I tried a different timer out of a working unit and still have no heat. I am not sure about checking power separate between each wire. I have a black wire at the heater on one side and the other side comes from the temperature control sensors on the blower and the heating element. With all wires cisconnected on the heating element, I still get continuity through the heating coil. I get separate continuity through eaxh of the temperature controls with the wires disconnected. I also get continuity through them through the heating coil.

16

Again Thank YOU

I solved the problem. I checked the wiring diagram and found that the wire that I had mended came off from the motor to the Heating coil, probably while I was working on it. I had to take out the drum to find that it had disconnected at the motor. I reattached it and found heat. However I now need to put it back together. Wish me luck.

It is back together and working.

GOOD JOB!
