New China built motor should have worked if you installed it, overload was just of a little different design.

 

One has the overload completely hidden in black plastic switch housing with wires running to connection points, other with exposed overload has a buss bar going directly over to exposed overload then the black wire off overload into motor windings.

 

And it's not 1/25 rpm - the top of the 7 is just in light print - 1725 rpm.

Actually I did install it. I left the drum out so the motor would not have a load on it and it ran for one 60 minute cycle and I started it over. It stopped running after about 25 minutes.

I am working on a Kenmore Mod. 110.64722400. This dryer when set on 50 minutes will run 20 - 30 minutes and shut off before the cycle is complete.

Has this Dryer ever worked OK for you at this location ?

OR is it a "new" installation ?

Yes. It has worked well there since day one. The new motor from Repair Clinic has been tracked to arrive here Saturday.

NOOOOOO! The motor from Repair Clinic came in this morning and I installed it. It ran about 35 minutes and shut off. What do I look for now?

The dryer has ran in that same spot in the garage for over 20 years with no problem....BUT, this is Texas and it is getting hot! After reading this post, Early this morning I set a fan in the dryer housing aimed straight at the motor and it ran a 60 minute cycle without stopping. I tried it again this afternoon in the hot part of the day and it stopped every 10 minutes.

 

 

Did you try the fan trick again?

 

Any dryer motor will trip the internal thermal protection if it's running in an environment close to or over 100F.  

 

The difference between the chinese motor you had before and the OEM replacement is that the OEM motor will simply stop running without frying the motor winding varnish like the chinese motor did.

No I did not use the fan. I completely assembled the dryer and checked to make sure there was no resistance turning the drum. I also replaced the felt seal on the back of the drum as it looked worn. It is hard for me to believe that the ambient temperature is causing this problem because we have ran a dryer in that very same spot since 1989 with no problems. I am not sure how old this dryer is but we bought it new and it has ran right where it is now since then and it has been a lot hotter than it is right now. Is there anything else this can be?

try running the Dryer on a full Air-fluff / no-heat cycle

OK. The dryer has just run three 30 minute cycles back to back on Air Dry (no heat) without stopping. What does this tell us?

seems the Motor is OK

did you ever test a normal heat cycle with the Vent disconnected ?

also, what are the Vent temperatures ?

I took the vent off and turned on the heat cycle. It ran for 25 minutes and shut off. I was not on top of it when it shut off to check the temperature at that instant, but I monitored I for a couple of cycles and it was going down to 115 deg. and going up to 160 deg. What is normal?

that sounds about normal temperatures

 

Dryer Vent 4" diameter

Vent should be rigid metal.
Short lengths of flexible metal may be OK, if not crimped when moving the Dryer into place.
NO plastic
NO PVC
NO screws
Foil Duct Tape is OK.
With an empty load, Timed Dry, High Heat, the vent temperature should cycle somewhere between 135F and 160F
Check / clean the Dryer Vent
Disconnect the Dryer Vent and check for good air-flow there and where it exits the house.
Check the Vent air temperature at the back of the Dryer.

If you have a Harbor Freight Store near you,
$ 3.99 sometimes on sale for $ 2.99

It is running a flexible metal vent tube...the same one that has been running for years. I took the tube off and cleaned it completely out all the way including where it exits the house. I also took off the lent screen support and cleaned it out as well. The readings I posted were taken right at the point where the air comes out at the back of the dryer with the tube removed. The thermometer I used is very similar to the one you have pictured only it is a digital meat thermometer. In a little while I will start the dryer again and monitor it until it shuts off. Maybe for some reason the temperature climbs excessively at some point causing it to shut off. Is there anything else you can think of that will cause this?

I set the dryer temp at med/high where it usually runs. The timer was set for 60 minutes and it ran for 35 minutes before shutting off. At this shutoff point the temp was reading 121 deg. It would not restart for about ten minutes. After restarting it ran for about 17 minutes and shut off. This time it started right back up. Ran 3 minutes, stopped and then started right up.  It stopped a couple of more times but started right up every time. During this process the temperature ran consistent from about 114 deg. - 145 deg.

 

I set the dryer temp on high and the timer for 60 minutes. It stopped after 30 minutes and at that time the temp was showing 132 deg. It ran pretty consistent between 123 deg. and 153 deg. It ran 15 minutes and shut off. It started right back up. It shut off several times as before but started right back up each time. 

 

I set the temp on low/delicate heat and it ran the same as with the other settings. The temp ranged between 110 deg. and 144 deg.

 

In each of the cycles it kind of stumbles a time or two just minutes before it finally shuts off.

 

Should the temperature differ more between the heat settings?

 

What do you guys think?

there may be too much friction on the Drum causing the Motor to overheat,

more so when the Dryer adds addition heat

It was shutting down the same way without the drum in the dryer.

there's not much else ..

Motor

friction

heat

 

voltage / wiring (had been working OK before)

Check the voltage at the Motor

maybe Blue to White

OK Grand Master, This grasshopper needs further instruction. I have a great multi tester. I can do wonders checking on automotive problems but I haven't got a clue on how to check the motor or the wiring on a dryer. Do you have a tutorial for this?
