Thermistor Parts

• Not drying dishes properly

My Whirlpool dishwasher (wdf520padm3) started leaving food on dishes and not drying dishes as well as it used to, even when I ran the 'high temp' and 'heavy' cleaning options. This started happening after about 3 years of operation. To try to diagnose the issue, I started the diagnostics cycle (see below for instructions on how to do this). However, the 'Clean' LED is also not working on my dishwasher, so I was unable to read the error code after the service cycle finished. I decided to... Read more

• Too warm
• Doesn't shut off
• Fridge runs too long
• Freezer not defrosting

Fixed it by replacing the electronic control board. Only 30 min. to fix. (See further down for effort to diagnose the problem.) Most of this "fixing time" was spent removing the control panel to access the control board that is attached to it. My freezer has the control panel located in the top center of the door. The only way to remove the control panel is to pry the panel out of the door using a thin-bladed putty knife.The instructions provided were very good in explaining the process;... Read more

• No heat or not enough heat

I replaced the "heating element" which was bad.........as well as the "Thermst-fix" and "Thermal Cutoff" which are located on the side of the element mounting location while I had the dyer all opened up and the element mounting tube removed.......I also replaced the Dryer Thermister which is located on the top of the blower fan.....To get to these parts, you must open the top of the dryer which has spring latches on both sides of the front corners... they need to be pressed in (use a putty...

• Shuts off too soon
• Too hot
• Takes too long to dry
• No heat or not enough heat

My appliance repair guy checked out the problem, but the stack washer dryer required the contractor to dismantle the cabinet to allow the repair to occur. So i wanted the parts available for the repair, so we would not have to have the dryer pulled apart in a small space for an extended time i ordered the parts on Friday afternoon and they arrived at my home before noon on Saturday! The contractor and the repairman were able to coordinate the repair on Tuesday morning, and though the... Read more

• Fridge too warm
• Frost buildup
• Doesn't shut off

Poped off plastics caseing inside the frigerator. Unscrewed 4 screws holding black fan inplace. Followed yellow wire to locate white sensor. Need to be careful not to break styrofoam, don't force it, it should seporate from plastic easy as long as the 4 screws are out. Swap it for the new one and button it back up. While I was in there I replaced the defrost sensor and the other sensor next to the heating rod. Also I know there is an issue with drain hole plugging up with ice so I extended the... Read more

• Won't start

Ordered a new thermal fuse from your website last week and installed it three days ago. This is the second fuse in one year that needed to be replaced. The dishwasher was purchased new in 2012. Relatively easy to replace. Your website had a you tube video that showed how to replace it. Power came back on the control panel, but the start button (not a button, but a touch screen) would not work. This is the second time in two years that the control panel had to be replaced because the start... Read more

• Too hot
• No heat or not enough heat

The heating element had a break in the heater coils, so I replaced it with a new one from Appliance Parts Pros. I also replaced the thermal fusible link and thermostat switch because they were so cheap it just made sense to go ahead and do it while I was in there. I also cleaned every nook & cranny in the dryer, then cleaned out the vent piping- which was about 100% clogged. The video's of how to tear down a dryer were indispensable to this repair - along with APP's always having the right... Read more

After reading the reviews of others, I ordered and replaced the heating element, thermostat, cut-off & the moisture sensor bars. It was a success! The element was definitely bad on one end, the wire was burnt in two pieces. Now it doesn't take 3 hours to dry a load! Well worth the money I spent. Easy to fix & do it yourself. I watched the video before buying the parts just to make sure that it was something I wanted to tackle. Very easy with the video. Great job Appliance Pro's! Read more

You can do this! Although an Art Director by trade, I like working with my hands. I’m adept at working with tools and following instructions. In today’s disposable society, I prefer fixing things. That said, this has to be the easiest repair I’ve ever attempted with the largest cost-savings versus hiring a professional. My brand new dryer had been in use fewer than six months (average 6 loads per week) when suddenly the dryer would not heat. The drum would spin, there were no error codes, and... Read more

• Freezer not defrosting
• Fridge too warm
• Freezer section too warm

This was a 2000 model so rather than just replace the defrost timer which was visibly burnt on the terminals, we just did everything. The cold control, defrost timer, thermostat, defrost heater and the compressor capacitor were all replaced. I had the same issue on my older unit and tore it apart replacing one item at a time over a three month period so on an older one i suggest do it all while it is apart. Read more

First ran the built-in diagnostic tests. Got error code indicating that the inlet thermistor was open. Removed lower access panel and did continuity checks on the inlet thermistor, thermal cutoff and heating element. Even doing these checks is very difficult on this model due to the location of these parts and the limited access through the so-called access panel. But was able to get an open reading on the heating element, so I knew that at least that part was faulty. Could not get a reliable... Read more

• Too hot
• No heat or not enough heat
• Takes too long to dry

Replaced the thermostat and fuse it could have been either of them that was causing the issue - and now it works like a charm. Read more

• Shuts off too soon
• Too hot
• Takes too long to dry
• Won't start

Recommendations have fun and a bucket to prevent losing parts. First watch the videos, practice disassemble and reassemble the dryer drum. Make certain you have a good screw driver and spatula from kitchen (could not find my putty knife). Secondly, clean and inspect everything, make sure the motor bearing and belt pulleys are in good condition with little or no play. Third after you have confidently disassembled, vacuum cleaned, inspected all the worn parts, grease the motor and pulley,... Read more

I watched the Appliance Parts Pro video and saw that it was a job that I could easily do. I ordered the Rotor Position sensor switch for about $21 on a Monday and it was delivered by UPS on Wednesday. The process was straight forward: 1) remove the back cover from the washing machine (4 screws), 2) remove the main bolt holding the magnetic drum on the motor; 3) remove the 6 bolts holding the coil on the motor; 4) remove the ground screw and wire harness clamp screw; 5) take the old sensor...

• Fridge too cold
• Freezer too cold
• Fridge too warm

Toughest part of this repair is figuring out how to get things apart. Amana doesn't provide you a repair manual showing how to disengage the various plastic covers. Initially disassembled the bottom freezer compartment so I could get to the evaporator coils; they were completely frozen in block of ice, restricting air flow to the fridge above. Obviously, the auto defrost cycle had not been running, or was short-cycling. Manually defrosted. Found this link for running diagnostic tests on the... Read more

Replaced fan motor in fresh food section, easiest repair I have ever made, took longer to get shelves out than replacing motor.. Read more
