CustomerDennis from Purcellville VA

The dryer burner wouldn't fire

Checked online for symptoms.
Pulled panel from front of unit (no tools required)
Vacuumed all lint from unit to see if that was a problem.
Removed the exhaust port which comes off with 3 hex head screws.

Based on the symptoms, I pulled the wires off the thermal fuse and did a continuity check on it. There was no continuity, so I knew I needed that part. Since a common reason for that to fail is the cycling thermostat allows the dryer to get too hot, I replaced that thermostat as well, just to be safe.

Due to closeness to the drum, I had to use a socket to remove the hex head screws on the two electronic parts.

Total time was about 40 mins. to diagnose and 20 mins. to replace the parts and verify correct operation.

Dryer would't heat up and noticed a smell of something very hot just prior to dryer not heating up.

Prior to ordering parts i moved the dryer out and took the back off the dryer with a nutdriver. I noticed right a way the heating element was damaged and burnt up. I ordered the above parts and recieved them in two to three days. the parts on my dryer were easy to get to and I just matched up the parts i recieved and replaced them one at a time. It only took a nit driver to remove them and plug the wires back in to the new parts.
the dryer works like new again.

Bad disposable fuse & possible defective thermostat

Unpluged dryer power cord.
Removed lower front panel (two snap clips at top of panel)(Rear panel cannot be removed from this dryer). Removed blower/filter housing (held by two screws). Found blown fuse by using an ohm meter across the fuse terminals with one wire removed - no continuity. When new parts arrived, I removed two wires from fuse and four wires from thermostat. Removed two screws holding fuse and two screws holding thermostat, and removed both parts.
I then reversed the above procedures.
Dryer works great!
Total cost, including shipping, was $47.76

CustomerTimothy from Anderson IN

Dryer would spin but no heat

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...)

Dryer would leave clothes damp

First, I unplugged the dyer and then I removed all of the screws for the panel that covers the rear of the dryer. This exposed the cycling thermostat's location. I then removed the wires, one at a time so I would be able to put them back on in the same place. Then I removed the one screw using a nut driver and then put the new cycling thermostat in place. It was pretty easy.

CustomerStephen from Wilson NY

Poor dryer performance and slow drying!

I knew that the dryer needed a new belt and since the dryer was also failing to dry the clothes in one cycle, I decided to replace the three thermostats, figuring that I might as well do all three if I'm going to open up the dryer. I downloaded a schematic of the dryer from the Whirlpool web site, which helped me to order the right parts and see how I would be able to make the repairs. Once I figured out how to get to the drum for the belt replacement, installation was quite easy.

First step was to unplug the dryer, remove the vent hose and remove the back panel with a nut driver. Once the back panel was removed, it was easy to see all three sensors. The heating element unit was easy to remove - two screws. This made it easier to replace the sensor. Each sensor was shaped differently, making it easier to decide what went where. This normally would not have been a problem, but the part numbers have changed for this dryer. I could have also cross referenced the parts by using the partselect.com web site.

To access the dryer drum, I had to remove two screws on the back of the dryer that are located in two tabs that hold the control panel to the dryer cabinet. Once removed, it was easy to lift the top of the cabinet and swing it up and against a nearby wall for support while I replaced the belt.
I removed the old belt from the motor pulley, and then just removed the whole drum. I placed the new belt around the drum, placed the drum back in position. With my wife supporting the drum, it was easy to bring the belt through a guide and slip over the motor pulley. Then, I rotated the drum manually to make sure the belt wasn't twisted.

After ten minutes of putting everything back together, it was time to plug in the dryer and test it. I did it without a load first and checked the vent for hot air. After that, we did a couple of loads...one on high and one on perma press, and when the cycle was over, the clothes were dry!

Delivery time from PartSelect was super fast! Prices are excellent, and I really appreciate such a helpful web site. Anyone with a small amount of mechanical ability and "do it yourself" experience can save $$$ by fixing it yourself. Having someone service this dryer would have cost me more just to replace the belt.....let alone the added insurance of replacing the sensors. And, I learned that if the heating element should fail, replacing it would be a snap, and would start with a visit toe partselect.com!

CustomerJennifer from Charleston TN

Clothes took way too long to dry (1-3 hours)

The first thing I did was google "whirlpool dryer repair drying takes too long" to determine all of the possible parts I needed to order (the result was 3 possible parts, a heating element and two different thermostats). I then went to www.partselect.com (I'm a repeat customer) and searched the parts using the dryer model number listed just inside the door. I then printed the dryer model diagram off of the www.partselect.com website to determine the location of all the parts and how to replace them. Our first purchase was the new heating element from the www.partselect.com website, received it in just a couple of days and replaced it, but that did not fix the problem. We then ordered the two thermostats, again received them in 2-3 days, replaced them, and were drying clothes in <30 min. in no time! All we had to do was unplug the dryer, disconnect the vent hose, take the back off, unscrew each thermostat, disconnect the wires, install the new thermostats, reconnect the wires, screw the thermostats back in place, replace the back cover, reconnect the vent hose and plug the dryer back in. It took <15 min. for the complete repair! Thanks, www.partselect.com! I will continue to be a repeat customer!!!!!

Dryer would not run

First I checked for power at the outlet (240volts-power good). I then removed 9 screws holding the back cover. I then turned the timer to run position and pushed the start button this allowed me to hear the timer andvance. So I disconnected power to the dryer and removed the wires to the thermal fuse. I then took a ohms reading across the fuse...it showed open. Removed one screw replaced fuse.
