Universal Freezer Thermostat WPF-20, Mini Fridge Thermostat, Temperature Control Repair Parts, Compatible with WPF16, WPF18, WPF22, WPF24, WPF30, Stainless Steel Shell

OK, strap in as this review is more of a step by step since documentation as a whole is poor and reviews here are really hit or miss. Keep in mind this part is pretty much universal so there are some steps required to calibrate for your use and appliance.I used this part to replace the OEM thermostat in my KitchenAide wine cooler - essentially a mini-fridge with a glass door. (As stated earlier, there are different variations of this part that will replace other OEM part numbers so do your research between WPF-10, WPF-20-, WPF-30, etc...)I diagnosed OEM part failure (compressor not starting) by jumping the compressor wire (blue in my unit) and load (black) together, bypassing the thermostat, which started the compressor. After the process below things are working well and I will update if that changes.Installation was straight forward: unplug cooler, unbolt the old part, unplug wires, and plug BLUE wire in the new unit's terminal marked C and the black in the L terminal. Leave the new part loose (unbolted) until final adjustments are completed - just make sure wires are secure. (Electrical tape helps)1st issue I ran into was the original thermostat probe wire (capillary) was affixed to a bracket on the bottom-backside of the cooling coil in the fridge. Carefully loosened the 2 screws and unwound the probe wire and completely removed the old part. The new probe wire was just a bit shorter, so it took one less wrap around the bracket, but secured in fine after tightening the screws slightly.With the new part connected, set main temperature dial in the middle and powered on and ran for 30 mins to let cooler chill. Using an internal thermometer, I found the temp quickly dropped below freezing. Unplugged power and 1st adjustment was a full turn CLOCKWISE on the temp. range adjustment screw (on the side of the new part). Plugged back in and ran again, but still dropped below freezing. Repeated the previous adjustment and this time the temp settled at 37 F. This is great as there is plenty of room on the main dial as it is still set in the middle of the adjustment range.I next observed that the cooler held an internal/ambient temp of 37 F with no fluctuation, but to achieve this the cooling cycles were very short and often. The compressor would kick on for 1 minute and then shut off for 2 minutes before turning on again. This would surely burn out the new thermostat quickly and possible damage the compressor. This is where the 2nd adjustment screw comes into play. The delay adjustment is on the rear of the unit (opposite the main dial) and is smaller than the temp adjustment screw so use a precision philips head screwdriver. Unplugged fridge and I gave delay screw a half turn COUNTERCLOCKWISE. Plugged fridge back in and let it run through 2 cycles to reach temp and then started my timer again. This time, the compressor kicked on for 1.5 minutes and shut off for 3.5 mins. Progress, so I repeated the adjustment, but turned the screw 2 full rotations COUNTERCLOCKWISE. Next time the cooler ran for just under 2 mins and shut off for almost 10 mins. Now that we're getting closer to ideal cycle times, the final adjustments will be keep the cooler in range. 2 mins on / 10 mins off allowed a 3 F degree swing in the cooler which is good, but the range can be a little higher to increase energy efficiency. 5-7 degrees was achieved after final adjustment of 1.5 more rotations of the delay screw. This has the compressor running for about 2.5 mins and off for about 18 mins. Turning the main dial a bit colder, clockwise, temps range from 35 - 42F.After adjustments complete, bolt in the new unit to finish.Since there are many different versions/variations of this part some of them may not look the same, but they should all share the same concepts. I have attached a technical diagram for a very similar part I found online. This was a big help to me so hopefully it is equally useful to others.Give yourself a few hours to install and adjust. I worry that those who simply throw this part in without taking the time to make the proper adjustments will find themselves in the same spot in the near future after this part fails from the oversight or worse the compressor burns out.March 21, 2022Update:Still working well, but after moving the cooler into the house after we converted our formal dining room into a den with a bar I decided to make a small adjustment - not needed, just me being compulsive.I did not post this review for any other part numbers, but if you are here reading for any of the WPF units, this review/guide does still apply, but your connections may be different and you probe/thermo wire may be a different length.July 26 2022

We bought a cheap chest freezer from Sam's Club, and the thermostat went out in the first year. I bought this to replace it, and it's been 3 years. This thing is still working great.

It works great and at a great price.

It worked well I had to mount it different than the original and didn’t have a knob with it but it worked fine.

Worked great in my mimi fridge.

Rapido envio,buen articulo.

Not cold enough for freezer use.

Similar to other reviews, you have to study and adjust. There is a temperature range screw and a duty cycle (on/off frequency) adjustment. These are Hugely Helpful! Other units I purchased would not work for my application for a beverage cooler, where the temp ranges are typically higher. My unit's compressor would just run non stop for days struggling to try to get to the lower temps that it's just not designed to do.Suggest putting the unit in the fridge with the thermistor lead just coiled in the main chamber. Run it and adjust the screw until you get fairly close to your desired range.NOTE: One issue when I did install the long probe through the tub it places the sensor on the back wall, which gets a little frosty and colder than the rest of the fridge. So, this required a little more tuning and adjustment as the fridge temp climbed back up a bit.Eventually over a couple days you will get it dialed in where you want, be patient. At least this unit has adjustment screws other than just the main knob.

Excellent part for bar fridge. Replaced broken one that was freezing all the pop cans. This one was the exact replacement. Fridge now keeps pop cold and none have frozen since the repair.

الترموستات عمل بالشكل المطلوب والحمد لله

J'ai besoin de coupe les terminaux un petit peut (les connections pour mon frigo sont plus petit), mais après je le monte sans problèmes. Le fil pour le sonde est un peu trop longue (ne coupez pas!) mais c'est pas grave. Dans cet modèle, il y que trois connexions, il terminal terre (dessous) et deux pour faire un interrupteur (en haut; courant secteur donc n'oubliez pas de débrancher). Un réparation de dix minutes.C'est un choix simple. Moins que quinze euros pour un thermostat de remplacement, ou plus que deux cent euros pour un nouveau frigo?Il est en place maintenant pour quelques mois, aucun problème. Le plateau haut de mon petit frigo reste bien autour de 1.5C.

Used to repair a boat fridge was a direct replacement for the fridge shown in photo. Big saving
