Dryer wouldn't start

After a couple hours of internet searches, I deducted that it had to be one of four parts. However with the parts i needed, if I replaced one , wisdom was to replace all four of them. So I ordered my parts form the dealer except for the Thermal fuse because they were out of stock. I stumbled across AppliancePartsPros.com accidentally. I will say that one the part was very affordable. Secondly, It arrived before the manufacturer's parts I ordered the day before. The repair was very easy and literally took no more than 15 minutes. I would recommend AppliancePartsPros.com to anyone that wants to save themselves the high cost of having a repair person come out. The parts are quality, the shipping is fast, and the website is easy to use.

Clothes dryer was running with no heat

Looked up the most common causes online. Used a multimeter tool to check the circuits and found the thermal fuse was blown. Ordered the part from Appliance parts Pros. It was cheaper and arrived faster than the company who makes the dryer. 5 minute job, will order another fuse to have on hand.

The Thermal Fuse is an OEM replacement part for Whirlpool dryers. This easy-to-install thermal cut-off is designed to shut down your dryer when temperatures become too high, protecting the appliance from overheating. It's a one-time fuse, meaning it cannot be reset and needs to be replaced. It can be tested for continuity with a multimeter.

Causes of Bad Thermal Fuse

  • Excessive lint buildup in the dryer vent
  • Poor air flow causing overheating
  • Failing to clean out the lint filter regularly
  • Faulty heating element or drying cycle thermostat


Don't let a faulty dryer leave you stranded with wet clothes! Replace your dryer's Thermal Fuse to get back to using your dryer worry-free. This OEM Whirlpool part can also be used on Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore/Sears brand appliances.

18% of the time Dryer Door Catch

Dryer door magnet was broke dryer door would not close properly

First I googled dryer door parts and found your website. Entered model # and what was wrong with the door. Up pops the site I needed complete with a video on how to change the part and how to order the part. Watched video and then ordered part, relieved I didn't have to take the door apart! Watched video again just because. Part arrived very quickly right to my front door! Watched video one more time just because and changed the part. Only took a few minutes and saved me a home repair cost. All under $15.00 for part and shipping! Thank you!

Dryer door latch broken

As a 61 year old female with long fingernails and NO experience, I was nervous about trying to repair my door. Your website was easy to understand, so when I entered the name of my dryer it took me right to the part I needed. There was also a video showing me exactly how to make the repair and after watching it twice I felt I could do the job. The price seemed reasonable and I ordered on the spot. Part arrived the very next day and I watched the video one more time. Low and behold I did it myself. I am very happy with the service and product. I highly recommend your company and will use again should need arise.

My housecleaning client's dryer door catch was broken she was going to call a repairman

I got the model number, looked up the part on your website, watched the video on how to fix it, ordered the part, then took it to her house and repaired the dryer.

The catch of the dryer door needed to be replaced it was broken

Removed the old, broken catch with a putty knife (which looked at lot easier in the video) and installed the new catch.

The plastic insert on one side of the dryer door broke and the door would not close

I didn't. My wife removed the door and we located the problem, then looked up the model number to determine which part was needed. Once that was done, we went online and ordered the part Monday night and had it just after lunch on Wednesday. My wife again did the final repair and everything works fine. In this case, the DIY worked great and we didn't have to bother a certified repairman.

The Door Catch is an OEM part for Whirlpool dryers designed to securely hold the dryer door closed during use. This small part ensures that the door latch engages properly, providing a tight seal to prevent heat from escaping and ensuring the dryer operates safely and efficiently. Made from durable materials, the door catch is engineered to withstand the frequent opening and closing of the dryer door.

Symptoms of a bad Dryer Door Catch include:

  • The dryer door not staying shut  
  • Difficulty in closing the door 
  • The dryer failing to start due  

Causes of failure can include normal wear and tear from the constant use of the dryer, damage from an external force, or misalignment from the door being improperly closed or hit. Over time, these factors can lead to the weakening or breaking of the door catch.

Replacing a faulty or worn-out Dryer Door Catch ensures the door remains closed as required during use, preventing potential hazards. This OEM Whirlpool part can also be used on Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore/Sears brand appliances.

This catch is the female piece on the door. For the strike on the front panel that inserts into the catch order W10295405.

11% of the time Dryer Repair Kit (most 29 Inch Large Capacity Models)

Dryer was squeaking very badly!

I disassembled the dryer, cleaned all the lint out(it was everywhere and I'm surprised it had not caught on fire), sprayed lubricant on the idler pulley and the rollers. Then I put everything back together and used the dryer. It was quiet but, short lived. I bought the "Dryer Repair Kit" from AppliancePartsPros. It had a new belt and idler /tension pulley that I may not have needed but, I thought, "if I'm taking it apart again, I'm replacing everything!" I followed the video instructions and the dryer is now like new. The plastic retaining clips (4) for the rollers were much more difficult to remove and replace than shown in the video. Other than that, everything went EZ PZ. My wife came home at the end of the job and helped me by holding the drum in place while installed the front of the dryer. I don't know if I could have done it alone. I know we saved a bunch by doing ourselves AND.....the parts came in less than 24 hours. I could not have scheduled a repairman in that time.

Broken drive belt

Ordered your repair kit based on my model number. It arrived 2 days later, unfortunately it was short 4 nylon and one metal retainers. I called and was apologized to. The CSR quickly found my order and said a new parts kit would go out to me the same day. I was only looking for the missing parts but was politely told that if a customer has an issue she is there to take care of it. REMARKABLE! The new kit arrived in two days with all the parts and the problem is solved. Incredible service in this "to bad for you society". The video of the repair I was performing was very helpful. I'm very pleased.

Not heating

I ordered the heater element in my Whirlpool Estates dryer, watched the video and had it changed in no time. I also replaced the belt assembly. Appliance Parts Pros delivered!

Dryer making noise

Getting the dryer repair did the trick. Now I have a old dryer that sounds like new. A special to the person who took my order, she suggested the kit for me. Plus the parts were less expensive than from another source.

Dryer was making a lot of noise

Drum support rollers - actually the dryer repair kit came complete with the lock washers support wheels pulley and belt.

3% of the time Terminal and Wire Kit

Fried terminal block

My daughter moved into a new home. During the move the dryer cord terminal screws somehow went missing and her brother in law substituted regular screws that worked but did not make a secure connection. Eventually after a power outage when power was restored the power surge was more than the substitute screws could handle and it melted some wires. The kit that I ordered made a safe and a properly secured repair. Suzanne took the order and was a tremendous help in getting the correct repair part. Excellent technical and customer support by Suzanne!

Electronic Control Board

F1 error

The dryer would not run because of the F1 error. I replaced the Electronic control board. It was very easy and fixed the issue.

F1 error code

I ordered the Electronic Control Board in hopes that it was the cause of the F1 error I was getting on my dryer. Sure enough, it fixed the problem! I pulled up a video on youtube that showed how to replace it and it didn't take more than 15 minutes. Tip: before disconnecting any of the wires, take a photo so you can reference it when you start reconnecting them.

Dryer quit working

The service papers inside the top of the dryer said the fault code meant a bad control board. I found a control board quickly on APP website and ordered it. I received it the next day and I then found there is two boards and I ordered the wrong one . I immediately ordered the correct one. It arrived next day and in a few minutes I had the wife back in business.

Dryer would not start had code F1.

Received new part quickly from Appliancepartspros, installed in less than 15 minutes. Dryer works like a new one.!..

Dryer was giving the "F1" error code

I bought a new control panel for my dryer. Followed a YouTube video on how to remove the old one and install the new one. I needed only a screwdriver for the job. It worked great! No problems or surprises.
