7MMEDC300BW0 Dryer - Instructions

When the problem first came up, I took the dryer apart without first looking up any instructions. This wasn't difficult, but didn't realize when removing the fan from the motor, there is a square lug as part of the fan hidden by the rear clamp securing the motor. I was able to remove the fan by holding the motor shaft with a crescent wrench and removing the fan by hand, but was difficult and gloves were necessary in case the fan loosened quickly and my hand came in contact with the sheet metal (very sharp).

I took the motor out and attempted to clean it as it was loaded with dust as was the dryer internals. I tried to lube the motor bearings and appeared to free up, but the sight of metal shavings on the rear bearing seal had me concerned. This ultimely did not work and was trying to buy some time until the new motor arrived.

This is when I looked up the motor part number and found that Parts Select had the part number in stock. I ordered the motor on a Saturday afternoon and got a quick response acknowledging my order. The motor shipped that following Monday from Fresno and arrived on my Southern California doorstep Tuesday. These guys have their act together and are helpful in making the repairs. In my case I did not have to make any adjustments to the wiring or the pulley for my model and replaced the motor the following weekend in about 45 minutes. Since I had the unit apart several times before replacing the motor, the installation went quickly.

The dryer is again working fine for a unit 12 years old and my wife is once again happy that we didn't have to purchase a new dryer.

I took the dryer apart ( using a repair book ) It was Super Simple to do I only needed a extra set of hand's to hold the drum in place while reassembling it. removed the hold down snap on collar's on the Motor ( after removing the Blower from the back of the dryer ( super simple. Extra set of hand's needed ) Reassembled in the same order. And now The Dryer work's like NEW..Shure Beat Buying a new Dryer..

Removed top and front of dryer then drum and followed the instructions in the package. It was a real simple procedure. I did additional cleaning while the dryer was disassembled.

I raised the top of the dryer, removed the front, the belt and the drum. Slipped off old rollers, installed new ones and new tensioner. Reinstalled drum and belt, bolted front back on and closed the top.

with both hands

Just follow the instructions the one was provided with Maitanace kit we bought from you.

Repair job took less than 10 minutes: 1) Unplug Dryer 2) Remove Lint screen and 2 Phillip screws 3) use flat putty knife to depress lid latches while lifting (latches located approx 2 - 3 inches from each side. 4) unplug defective door switch 5) remove 2 Phillip screws that secure the door switch. Reinstall switch repeating the above steps in reverse order and your done.

I disassembled the dryer once to clean the motor and compartment. After reasembly, the problem persistes. I ordered the motor and the second diasasssembly was accomplished in 10 minutes and the entire job took 45 minutes and the dryer was running like new. Tip- Leave the motor secured while removing the blower fan.

First I unplugged the dryer from 240V and removed the back cover upper (behind the switch) and lower (exposing the remainder of the parts)

Inside the upper section was a folded wiring diagram of the dryer (don't know if this was courtesy of Whirlpool or another individual, but it was a very nice touch.)

I did a resistance measurement across the heating coil and found out it was fine. I then plugged the dryer back in and carefully took voltage measurements from one phase of power (this was easily accessed where the power comes in to the dryer, just be careful not to touch or short the wires)

I had an assistant turn on the dryer (this makes things go a little faster, as you are behind the dryer otherwise) and checked for 240V across the heater coil.

Once I did not have this, I kept one lead on the left side wire (one of the power phases coming into the dryer) and moved the other lead to the left (as viewed on the wiring diagram) until I no longer had 240V. This identified the faulty component as the Thermostat High-Limit, non resetable.

I ordered the kit with the High Limit NR and High limit Thermostat (as both had to be bad). I also ordered the 150 degree cycling thermostat (although this was not necessary - for <$20 I opted to replace it as well)

Removing wires one at a time, each component is fairly easy to replace.

My only complaint is that with the combo kit, the wire attachment is a little different that the original component and requires you to cut an existing wire and crimp a different terminal to allow all three wires on the High Limit thermostat (250 degrees) to be attached. There is little to show you how exactly the crimp is to be connected (it goes on the smaller of the three wires - DO NOT CUT the jumper provided and USE A GOOD CRIMPER - not the $2 variety, or you'll be getting a new connector!!) The connector provided is designed for some strain relief from one connector to the other, however) An additional jumper with the appropriate connectors already attached would be a nicer design.

Also, make sure you do NOT screw in the smaller cover that covers the power in until you place the entire lower half cover back on the dryer (unless you want to take it off a second time, as I did...) as it uses a common screw to hold both in place.

Overall, fairly easy to do with a minimum of tools, straight blade screwdriver to remove stubborn wire connectors (esp. for HT thermostat 250), ratchet and socket for quick removal and replacement of covers, and a good T&B style crimper ($10-$20 at your local hardware and well worth it even if you only use it a couple of times)

30 minutes and done - the dryer now cranks out the heat and the advanced settings (Auto dry) work great - no more 2-3 times throug to get things dry.

If you have a minimum of mechanical ability and a little bit of electronic troubleshooting skill, you can check and repair this youself and save about an $80-$100 service call.

Thanks to Part Select for the diagram of the dryer layout as well!! (Schematic would be nice if available online, though!)

Shipped the part in about 2 days from order time, as well. Will be back (hopefully not soon, though, as something has to break first!!!)

Be safe and good luck!

(One last note: Make sure your lint trap is clear including the hose - either due to build up or a lazy kid...as this probably caused the failure as heat could not escape...)

PULLED THE DRYER APART TO GET TO THE MOTOR , REMOVED MOTOR , LOOKED FOR MODEL NUMBER OF DRYER AND DID RESEARCH ON WHERE TO BUY THE MOTOR AND BOUGHT FROM PARTS SELECT BECAUSE BOUGHT FROM THEM BEFORE

Half of my pulley was broken off so there were no wrench flats to take it off. I was able to remove it using Channel Locks and the 7/16 wrench shown in the video.

Hint: Use a one gallon ice cream bucket to hold up the drum while connecting the belt. It makes it much easier and gives you more clearance.

I found a video tutorial that explained the three things that are usually the problem when a dryer stops working. This showed how simple the task is. I used a multimeter to check the switch, to make certain that this was the part that needed replacement. This was part of the tutorial, as well. I ordered from PartSelect because it was recommended to me by an application that I use to find places where items are less expensive. The correct part arrived in a few days and it worked fine. I'm not a handyman by any means, but the tutorial showed exactly what needed to be done. It appeared simple and it was.

Everything worked perfectly---thanks to the suggestion of your call center agent. She suggested that since the replacement door handles were no longer available, I should consider repainting them--it worked like a charm. Please tell her she was a life saver. We rent that house in Fl and my returning tenants had complained about the discoloring refer handles. Thank you

After researching and finding correct replacement unit placed order and waited to receive. Screen is located top of dryer so replacement simple and fit was perfect.

I looked at the parts breakdown to see how it cam apart.

I tore the dryer down,
1. removed the door
2. openned the top
3. removed front panel
4. removed fron bulkhead
5. removed belt and drum
6. removed back cover
7. removed the ductwork
8. removed the fan (this is the hardest part, it is very tight on the motor with left hand threads, there are flats on the (inside of the dryer)fan where the motor shaft goes into the fan for a wrench and you can put a socket on the front pulley on the motor. I ended up just knocking the center out of the fan and replacing it.
9. removed the motor and cleaned the entire unit
10. reinstalled everything in reverse order. Note:I went ahead and replaced the idler pulley and the rear wheels that support the drum, and put a new belt in (just about
everything that could fail) I spent about $200 to keep a $1200 dryer in service at least another 7 years.
