Question:

How do I remove the old hi-limit thermostat and replace it with this one?

Gillis
Answer:

Hello Gillis, one side of the hi-limit goes onto the heater terminal and the other connects to the wire. Replace the old one on the heater leg with the new one. Best of luck with this repair.

Question:

Can I test this with a multi-meter? If so how will I know if it is still in good condition?

Question:

Dryer has been not really heating properly lately, having to cycle many times..today, zero heating today, tub turns, etc..just no heat...we found this site, husband used a tool to check the high limit thermostat, which we are ordering, my question is can you really check the heating elements. other than visual..it isn't glossy silver anymore, more of a patina kind like maybe what copper looks like as ages, no breaks in the coils, all looks good, not rusted, continuity of coil heating element was fine so we are guessing it maybe one of the two thermostats? thoughts?

Penny for model number Roper REX4635EW2
Answer:

Hi Penny, Thank you for your inquiry. It could be the thermostats, but I would also check the thermal fuse as well. I hope this helps. Thank you and have a great day!

Question:

My dryer is not working properly when I have it on “auto dry” but every other setting seems to work. You recommended first to check the vents and the blower but those are all in good condition and no clogging, where should I go to next? Would it be the hi-limit thermo?

Aaron
Answer:

Hello Aaron, the most likely reason for the dryer to not have heat, would be a damaged contact in the timer. I hope this helps!

Dryer would take forever to dry clothes, even on high setting

I ordered all the thermal sensors for the dryer. They arrived two days later and they were the correct parts. It took me about 1/2 hour to replace all three sensors and now the dryer works like new again. My wife was very pleased, so was I.

Heat in dryer very low, would take an hour and half to dry a load

First I called an appliance repair place. They charged me $40 to come out and said "the air vent might be clogged". I snaked it out and really wasn't anything in there. So I started thinking it might be a thermostat. After reading the reviews that others posted here, I said, "how hard can it be"? Thanks to PartsSelect putting a diagram (schematic) of the parts, I could see what I was looking for when I removed the back panel. So I took my nutdrivers out, disconnected the vent hose and removed the 10 or so nuts off the back panel & got it out of the way. Took out the vacuum cleaner and sucked all the lint out. Removed the housing where the heating element was and marked on both thermostats and housing where each wires went. As cheap as PartsSelect had the thermostats priced, I figured why not remove the guesswork by buying the highlimit and cycling thermostats and a new heating element too. One screw in each thermostat and out they came. Swapped wires with new thermostats and put them back. With the heating element...it was all one piece, so no fighting to get the element into an old housing. Just swapped them. Put the back panel on and reconnected the vent hose. Cost to repair: about $100. Time for parts to get to me: 2 days. Time to install new parts: about 10 minutes. Knowing that I have a dryer that runs like new AND saving a TON of money on electric bill....THAT is priceless. Thanks PartsSelect!

The dryer was working normally, just no heat

Very Very Easy all you need is a 1/4 inch nutdriver. 1st remove the screws from the back of the dryer. 2nd you will see a shaft like duct work. remove the 2 screws from this shaftway, lift out the old heating element and replace with the new element. Part select was right on target and fast. 2 days to recieve my order. I expected to have to buy a new appliance. Partselect made it possible to fix it like new for around $80.00

Too long to dry

First I removed the two screws that hold the element in place. I then pulled the element out about 3 inches and disconnected the two wires, then connect the two wires into new element, and put the element back in place, and put the back cover, now it getting really hot, and save me a lot of time and money on energy too.

There was no heat from the dryer

I watched the video on how to diagnose problem and then how to repair . Videos were very helpful. Also the parts were ordered on line and arrived in 2 days. Parts at a local appliance parts store were twice the cost of what I paid for the parts from PartSelect.

No heat in dryer

Once I unpluged the dryer and then removed the back cover, I located the heating unit and then removed the thermostat. Once that was done, I installed the new thermostat and connected the wires. I tested the dryer to make sure that it would heat. Then I replaced the back cover.

Damp clothes after drying....

repair was fairly cut and dry...if you have any handyman experience....the hard part was partselect web page...starts out easy to locate part if you have the correct model number....however after that it can be confusing as to what you are looking for part wise and if you have located the correct part....diagrams are helpful if you could see them and/or understand them or what you are looking for....as a novice can be fustrateing....even after calling partselect for help/explaination....other wise it went well for a repair and hopeful will get another 10yrs out of this dryer.....

Dryer was not heating

We pulled the back off the dryer and we weren't sure where the problem was exactly. So we pulled off the heating element and the thermostat. The heating element seemed to be burnt out, so we ordered that and the thermostat. We got the parts very quickly, so we put them in and found that the dryer still didn't heat. There was another thermostat (trip thermostat) that we decided to order and try...bingo...that was it. Now it works like a charm.

Dryer was blowing cold air

It's amazing... I fixed my dryer!! I am a 47 year old woman with no technical training, and I did it!

I live in a apartment and I bought the Whirlpool Dryer (Model #LER7646JQ0) USED for $150 about 6 months ago. The dryer started blowing cold air, so I called the place that I bought it from and they quoted me a price of at least $300 to fix the dryer.

After searching through google, I found the partselect.com website, and read the repair stories. I decided to take a chance. I ordered just 2 of the suggest 4 parts that could fix the issue, and the dryer did not work. The next day I order the other 2 parts, and that did it - my dryer was fixed.

The diagrams on the site were a little confusing to me (the dryers looks a little simpler inside) but it was easy to repair. I used a screw driver and plier to do the repair, however it would have been much easier if I had a socket set. I would suggest buying all parts suggested, and return the items you don't need. Here are the parts I used:

1. THRMST-FIX (Thermostat, High Limit 221 F
2. USE WPL 279838 (Heating Element (10" long x 6" wide)
3. Thermal Cut-Off Kit
4. Cycling Thermostat (Limit: 155-25) (Thermostat, Internal-Bias)

Good Luck!

The ice guide for our fridge was broken. No heat for the dryer.

The ice guide snapped right in 2 minute job.
With the dryer I had to remove the back of the dryer which was about 8 screws another 5 screws for the One time use thermal fuse, the thermal cut-off kit and the high limit thermostat. I used a nut driver and it took about 20 minutes. I am not sure which part needed to be replaced but seeing that I had bought all 3, I replaced all three.
The dryer works fine now.

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!
