      Having laid some theoretical groundwork in the last webinar, we're going to focus on practical considerations in this one. That means quick n’ dirty techniques for diagnosing sealed system problem using strategically chosen and skillfully interpreted temperature measurements.  Review homework from the first session on 10-2-2017. Home refrigerator practical design and operating rules-of-thumb useful for troubleshooting Practical application exercises Troubleshooting scenario exercise Techniques for making system temperature measurements for determining superheat and subcooling Sealed system diagnosis homework assignment (to be reviewed in the next webinar in this series) If you attended the first webinar in this series, this is your payday! We’re going to apply that keen, penetrating insight you now possess into money- and time-saving shortcuts you can use to diagnose real-world refrigeration systems on service calls.

Admiral Dryer AED4475TQ1

Recommended Posts

Adirondack Bob

Hi All, This is an Admiral Dryer Model# AED4475TQ1 that is completly dead. I tested the power cord, there is 240 volts at terminal block, the start switch ohms o.k., the thermal fuse is o.k., I installed thermal cut-out kit #279816. Still Dead. There isn't much to this dryer. The only things left are the timer and the motor. Any tips on how to tell which one it could be? Thanks, Bob

Did you check these parts with wires removed?

Did you check the door switch?

Wow you're quick! Yes, with wires removed. Checked door switch also. I tested everything three times! Just not sure how to check the motor or timer. This dryer is 20 months old...

and you checked the Neutral ? . . . . 120v to either Red or Black

The Thermal Fuse you tested... the white plastic one ?

Yes, I tested nuetral to both red and black on terminal block. Yes the white plastic thermal fuse. Ohmed it out then I jumped it out also. That was the first thing I went after. I searched for a broken wire somewhere. Like I said there isn't much to this dryer. I replaced the other thermal fuse and thermostat on the heater box also, just to be sure.

while the Dryer is set to run a cycle:

Test for 120v AC from each side of white Thermal Fuse to chassis (a good ground)

Test for 120v AC from each side of Timer Motor to chassis (ground)

I see. I took the wiring diagram with me. (I will put it back when I am done) It looks like the Timer is one side of the Thermal Fuse and the motor is on the other. I am not going back there until Thursday. With all the tests I have done so far, besides a broken wire, do you think it may be either the timer or the motor? Thanks, Bob

Ohmed out door switch. Trying to understand. Testing for voltage on timer side of thermal fuse will show if timer is sending voltage and therefore o.k.? And testing on motor side of thermal fuse means timer is sending voltage, thermal fuse is o.k., and voltage is reaching the motor?

What does testing on either side of the timer motor prove?

I know without the wiring diagram in front of you it is difficult to see what I see. I appreciate the help, Bob

You know most of your tstats and cutoffs, door switches, ect can b bypassed to confirm assumptions??? But if thermal fuse and doorswitch is good it's likely u have a bad start button part #3977456 to confirm carefully bypass to confirm!!!

Being bout year and a half old I would lean towards timer issue! Did you check your contacts on timer with the chart on schematic??????

I've had a rash of timers going bad lately in the newer Whirlpool branded dryers. I think alot of it has to do with the fact the timers are 240 volt timers rather than 120 volt timers with a separate relay for the heat circuit.

Is this a common Timer, and do you guys consider it truck stock? Also, is there a website that you can type in a part number and see a list of all the models that use that particular part? Thanks, Bob

Nawsir, I don't stock any timers. Too many different kinds and they're liable to sit in the truck for months and get damaged.

That'd be awesome! Midwest Timer may have something like that. I'm posting via phone right now or I'd post the link but just Bing em and you'll find em.
