BX20S5E-P1196502WE Amana Refrigerator - Instructions

I took a chance and ordered a switch that is next to the top of the door. looked for how to remove it easily done in ten minutes works fine last long time.

removed cover in back of freezer and observed that defrost cycle seemed to happen too often. In comparing the existing part # with the factory part, I determined that possibly the wrong part was installed previously. (it had a 6 hr cooling cycle with a 45 min defrost...spec said I should be 8 hr cool & 20 min defrost) I did research on applianceguru.com... well worth the 5 bucks! I ordered a timer & thermostat & purchased a special refrigerator brush to clean the coils on the bottom. Cleaned the coils, replaced the parts in about 15 minutes and WA-LA! the freezer started getting really cold, but the fridge wouldn't get below 55. but it FELT cold! I swapped thermometers with the freezer & found out the thermometer was faulty!!! I now have the cool control backed down to 5/7 & freezer to 6/7. temps are freeze 0 and cool 40. works better than since we bought home 5 yrs ago! research & troubleshooting took a bit of time, but by the time I ordered parts I felt very comfortable I had the right parts. All said, cost me about 40 bucks instead of probably $200 from tech... schematics from partselect.com were very helpful as well!!

Order the part from the Internet on Sunday, it mailed out on Monday and I received it on Tuesday. I unplugged the fan then undone 3 screws that held the fan bracket to the refrigerator pulled it out unscrewed 3 more nuts and replaced the fan on the bracket and I cut the old wire plug off the old fan and with 2 wire nuts put it on my new fan. Replaced the fan and bracket back on the refrigerator plugged it in and it works like a new refrigerator.

removed back cover, removed fan motor and replaced with new one. connected new power wires. worked right away

Removed timer kit (this was the second time for this part)/ replaced - this is a fairly simple job and take 5 minutes. The defrost thermostat take about 10 minutes to get to and take out the old one, replacement is a 2 minute job, unplug and replace, the longest part of this job is getting the back of the freezer off and then replaced, but it is fairly simple to do. Total time to diagnose about 15 minutes, replacement parts arrived in 2 business days, replacement time 15 - 18 minutes total. Recommend getting the thermostat and timer together. The first time this happened, only order the timer but I think the problem was the thermostat all along and the time seemed to be operating but when it came on every eight hours it tripped the circuit breaker Not sure which was really the problem, but all working fine now.

I was told to order the run capacitor and the technician thought it would repair the refrigerator; but it did not. The appliance technician had to take the run capacitor off and install what he called a "hard start" and the refrigerator is operating right now.

The refrig seemed warm so I checked the temp of some liquid with a thermometer. Readings were above 60 degrees and I knew food would spoil soon. I vacuumed the dog fur off the cooling coils underneath the machine to see if that would help. Nope. I realized cold air from the freezer was not reaching the refrig. The fan was working but no cold air was coming out. I figured a blockage either in the air duct from the refrig or in the return duct to the freezer. I didn’t see any blockage in the refrig section. I took everything out of the freezer and removed the back wall. The cooling coils were completely frozen solid with frost. Being a frost free machine, I knew there were heaters that were controlled by a timer that melted this frost away periodically and that this cycle was no longer working. I found a schematic on the web, maybe your site, and educated myself on the heater circuit. The circuit consisted of a timer, thermostat near the coils, and a cal rod heater all wired in series. The timer was easy to get to and being a mechanical device I figured it must be the culprit. I ordered one online. I checked its operation and it worked fine. Realizing time was short, I hot wired the cal rod around the thermostat and rotated the timer to its heat position. The frost melted quickly and I put the freezer back together and ordered a thermostat. I canceled the timer order. When it arrived, I installed the new thermostat and it has worked fine for the past month. A little colder than usual as I don’t yet have the settings back to where they were. I have checked the operation of the old thermostat. It’s supposed to close at 30 degrees and open at 45. I have done a continuity check on it by putting it in the freezer, letting it cool down, take it out, let it warm up and it seems to work fine. So I have doubts if I really solved the problem. Wire connections were tight and not corroded. Maybe the timer was hung up on debris that I freed by cycling it. I don’t think this is the end of the story.

After unplugging the appliance I needed to thaw a large ice buildup off the evaporator cover panel before I could even remove the panel. The freezer being on the lower part of the appliance has the evaporator mounted vertically and it was 100% encapsulated in rock hard ice. It took over an hour to thaw the ice and collect all the water with a shop vacuum, since the condensate pan began to overflow.
One thawed, I checked all wiring for good connection, checked heater, defrost thermostat, timer unit with multimeter. The defrost thermostat checked out fine after putting it into another freezer for a 15 minute cooldown, but I noticed a crack in the seal and suspected internal moisture and decided to replace that part. A simple plug in of two leads to the new part after clipping it to the evaporator, replacement of the panel, and the appliance was up and running problem free.
A workbench disection of the old part confirmed my assessment, it had internal rust and water and had failed causing the defrost cycle failure.

Removed panel and motor cover at rear of freezer compartment. This requires 1/4" nut driver. Removed motor assembly bracket and wiring, careful to note where ground, neutral and hot were attached. The entire assembly must be removed from the freezer compartment in order to swap new motor for old motor. Re-inserted assembly into freezer compartment, reattached wiring. Made sure all assembly screws were tightly fastened and wiring was correct. Re-attached panel cover and motor cover. I did note that a few of the 1/4" machine screws wobbled in the original holes; I used slightly larger, 5/16" head machine screws of identical length as replacements. New motor is much quieter. No longer sounds like a truck is idling in our home.

It's self-explanatory. The procedure is obvious; it's just a little difficult. The only hard part is attaching the mounting brackets to the fan. If you can't tighten the mounting bolts, loosen them and reposition the brackets. You might end up mispositioning them at first, because they are hard to reach.

Emptied unit and removed screws holding panels at rear of freezer compartment. Removed panels. Removed two screws holding motor. Made diagram of wire locations and fan blade orientation. Removed three wires and fan blade from motor. Took new motor and installed wires and fan blade to motor. Installed motor with screws. Test ran frig and reinstalled panels.

Most difficult part was finding where they hid the defrost timer. (it is in the left front under the fridge behind the kick panel.) just unscrew the two fastener screws from the front, tilt fridge up on one side, slide timer bracket back and remove. Unplug and remove timer from metal bracket. Replace timer and remount bracket.

Pop off six mounting screws and the ground screw. Remove the fan blade and reattach. Reinstall. Save yourself big bucks.

I took the cover off of the evaperator in the back of the freezer compartment and thawed the ice out with a heat gun. I then replaced the bimetal defrost timer I did have to change one connection as it would not plug into the harness.
I found the Defrost timer in the front of the refrigerator behind the filter cover at the bottom. Just one screw and a quick plug in and everything is working wonderfully. no more icing up

I emptied the refrigerator, pulled out the crisper drawers, removed the left side crisper frame and support post, slid in the new frame and post (no tools required), reinstalled the crisper drawers, reloaded all the food back into the refrigerator. I was done in less than 15 minutes. One of the easiest repairs I have ever had to do.
