Is the compressor dead?
 
I have a 2001 Kenmore 21' Bottom Mount Refrigerator (model # 596.71104101) (M14-71104)
I woke up one morning to find everything in the freezer defrosted and mushy. The fridge compartment was also warm.
1. I checked the breaker and power to the unit. All checked out, there is power to the unit, the lights and fans are on.
2. Checked the cold control dial located in the freezer compartment. All checked out. Switch was set to "4" (same for in fridge compartment)
3. Tested the cold control to ensure fans turn off/on. All checked out fine. Fans in freezer/fridge and at the back for the condenser are on.
I did notice the compressor was not making any sound.
4. Checked the defrost timer. Advanced the dial for a click, (in to defrost mode) then click again (out of defrost mode) still no sound from compressor, fans did turn on when out of defrost mode. While I was checking the timer, I also cleaned out all the dust and dog hair from the condenser coil. Perfectly clean!
5 Listened to the defrost timer when I clicked it out of defrost mode. No ticking sound. I thought the timer may be bad, so replaced the defrost timer with new timer. Even with new timer, no compressor sound.
6. Opened back of freezer to have a look at evaporator coil and defrost heater. No frost, ice or water of any kind seen.
7. Checked defrost thermostat for continuity with multi meter. (tested with ice water) No continuity, so I replaced the defrost thermostat.
Still, no compressor sound.
8. while looking in the freezer, I noted the ice maker was corroded. Replaced ice maker unit. I had also noted earlier, before freezer failure, ice was
"hollow". At this time I also tested the water intake valve at the back of the unit. No continuity. I will replace the intake valve once I get the freezer working. :)
Also while in freezer, noted the door gasket was not making a good seal. Replaced the freezer door gasket.
Going back to the BACK of the unit. I noticed that there is a Supco 3 n' 1 start replay on the compressor. Checked online on how to test the starter and compressor for continuity and ground and ohm- this part confused me! I tried testing the C, S and R and windings etc... ugh....
Not sure. SO.... I replaced the Supco starter with a new one, just exactly as the old.
Still, no compressor operation. More looking online. Maybe the COLD CONTROL thermostat in the freezer is bad? If I understand correct, this part controls power to the compressor.

I have spend just over $300 on parts to try and get this fridge going. What am I missing? Do I just have a worm out compressor? Any suggestions and help? Thanks soooo much!

Hi.

Remove the start devise from the compressor. Using the multimeter check continuity between three compressor's pins and between any of this pins and ground.
You should have continuity between pins and no continuity to the ground.
If the reading is incorrect - you have a bad compressor.

Post the results.

Simon.

Thanks Simon. I have set my multimeter to "sound" with continuity.
From C to R no sound. From C to S no sound. From S to R sound.
For ground, C to the compressor its self (with some of the paint scratched off to reveal metal) no sound. From R to the compressor sound and from S to compressor sound.

Do I also need to remove the green ground wire from the compressor, in addition to the 3 n' 1?

Looks like I have a dead compressor. :(

Hi.

You are right - it's bad compressor.

3 n 1 blew out the compressor windings, have seen this often. Lesson learned, Never use a 3 n 1 hard start on a domestic, fractional hp compressor.

Thank you richappy. I figured that is what did it. The 3 n 1 was there when I in inherited the fridge. I worked great for 4+ years. ugh.
Given what I have already invested to try and get it going, do you think it is worth the money to put in a new compressor with factory start/relay/ovrload?
I have about $300 into it now. I LOVE the fridge. Bottom freezers and great for our family.

Looks like on this site, a compressor kit for my model will run $200-$350. They I would need to find a tech to install. Given the cost of a new fridge with bottom freezer and what I already have into repairs for the one I have, would you suggest I replace the compressor?

enhouse3 11-30-2012 08:06 AM

Thank you Simon. Given what I have into the unit now, about $300. Do you think it is worth it to put in a new compressor? They go for $2-300 on this website, plus what a tech would charge to install. Suggestions?
I love this fridge. Bottom freezer works great for our family

You have burnout contamination. You can check servicers,but common charge us $600- 800

grumble grumble. Sad. seems like a waste of materials that will now go to a landfill or something. I guess I will remove all the parts I installed that are new.
I really appreciate all the help. Thank you!

My suggestion is also to get another fridge.

If the parts you recently replaced where purchased from APP contact our customer service for the return policy.

Simon.
