Dryer is sometimes not drying the clothes by the end of the cycle.

Here are the symptoms:
Sometimes the blower motor (separate motor on this unit) does not start up. Other times it does.
Sometimes during the cycle it groans and stops in the middle of the cycle. The drum keeps going as normal no matter what.
The blower will sometimes start back up and work.
When it is working, the clothes will dry and all is fine.
When it isn't, the heat shuts off and clothes don't dry.

Here is what I have tested:
Checked 240 Volt in = OK

Entered diagnostics by-
Powered up the unit,
Hit "Help"
Hold "My Cycles" and "Back" at the same time
Sometimes I get - Inlet Thermistor Problem
Sometimes I get - Blower Motor not up to speed
Sometimes - No error detected

I removed the blower motor and checked ohms:
Blue to Blue = 14 ohms
Red to Red = 14 ohms
Yel to Yel = 14 ohms

I powered up the dryer and checked the other wires on blower motor:
Black to Orange = 5 vdc (assuming this is encode in)
Black to Brown = 0 vdc when not spinning if it started to work I got voltage out (like 2.12vdc)
(I assume this is some sort of tach or encoder out of the motor to control board to tell it the speed it is turning).

When it wasn't spinning I was getting dc voltage across the red pair. It would start low and go up to 12 vdc then shut off for a while. When the voltage is there the motor makes a high pitched whine and it will jerk and shimmy and kind of lock the shaft. Sometimes it takes off and runs, then all seems fine.

Questions:
I see an access door on the back for the inlet themistor.
Can this part cause the blower to not operate?
How can I check it and what measurement do I look for?
I assume some ohms range related/depending on temp?

I checked the outlet thermistor when I had the blower out and it read 225K? I dont know if this matters or can cause the blower to stop?
It changed values when I held it in my hand and returned when I let it go.

Looking at the limited diagram in the control panel, it looks like it is either the motor or the inverter board but I am open to suggestions???

Hi,

I was wondering if you ever figured out how to fix your dryer? Mine is doing the EXACT same thing and I really don't know where to go with it next. I tried the inlet thermistor but that didn't fix it. It is drving me crazy!!:mad:

Nope no more suggestions. I did order and install the inlet thermistor but it did not fix the issue. We do not have an OHM meter (just a regular one I guess) but both the old and new inlet thermistor tested the same na-da! I don't know what the heck is going on.

[MODEL][/MODEL]You know it sure would be nice if GE would take some of the responsibility for these crappy blowers!!! Seriously I have literally obessed about this and found the same thing on website after website with people complaining about the exact same thing. I say we rise up against them and start some kind of petition. I would take a long time to get up a bunch of statements but until someone starts holding these companies responsible they are not going to do anything. I mean look at car companies they have to issue recalls and fix problems with their products. What's the difference with an appliance that you purchase for nearly $1000.00 and expect the d*** thing to work for at least 5 years!! I am going to do some research or contact BBB or something. I probably won't get jack for it but at least GE will know that these are crappy blower:p

Ok so I it is heat related. My problem with replacing the blower is the darn thing works. So it has to be something sensor/computer related telling the unit it is too hot and to shut off. Any suggestions out there?:confused:
