I have a 17 year old mini fridge that recently stopped cooling. Upon plugging it in, the compressor would hum for a few seconds and then the overload would click and trip open. Checked the protector, very low ohms. Checked the start relay, completely open. No rattles, but when I took off the cover the disc and contacts looked pretty bad. Wanting to make sure a new start relay was the right fix, I made a jumper for the start relay pins, and then plugged in the fridge just for 1-2 seconds and unplugged it, and the compressor started up and sounded normal. After watching your video and the troubleshooting I feel confident enough to order a new start relay. Thank you for sharing.

[@dwightlouandwynnmoodie4931]

great teacher! clear and detailed photos and explanations. I am an old DYI guy playing and learning how to fix the AC on our camper van. I learned from this video the importance of changing all capacitors and relays at once. I worked my way one by one and have ended up with a problem again, probably a new capacitor blown.

Recently had a Frigidaire mini-fridge that wasn't cooling. Compressor was hot and when the thermal overload reset, it was pilling 9 amps with an LRA of 11. I checked the PTC and it was reading about 50 ohms. I disassembled it and found signs of carbon/overheating on the run terminal/PTC contact surfaces. I scraped both surfaces down and got a reading of 9 ohms. I reinstalled it and the fridge started up with 1.3 amps while running. It continued working while I awaited arrival of the $10 replacement. It's running fine. Thanks for the great video which I found after I had repaired the fridge.

This is by far the most valuable video on relay fault finding on the web. Your instructions are the best and most easy to understand. Well done and thank you for sharing with all of us.

Today I changed burnt PTC Thermistor in my Samsung fridge. Your instructions mentioned to check the resistance between starter and running inputs (bottom two out of total three)of PTC. It should not be open. Guess what! Mine was open. Along with other tests I decided to chagned PTC for $15.00 from Grainger. It worked. Thank you very much for a very good explanation.

You said at 3:34 that the overload terminal has a "common" wire attached. Isn't it a red or hot wire attached there? On my fridge Kenmore 106 series, the red wire goes to the overload, then the overload plugs into the single prong which I think is common. I thought red was hot and common white.

Thankyou brother that's the best explanation 👍👍❤

[@seventyfive1]

This helped me fix a midea freezer that was DOA. All the parts tested out fine but i noticed the connection to the relay was very loose so I tightened up the connector and the compressor started humming along!

[@domjohnson2579]

My minifridge (danby) is not cooling sometimes. The compressor runs fine sometimes and other times it shakes and doesn't seem to be working properly. I have the round overload type in your video at 5:00mins model # B58-125 and cool it has 0.5 ohms resistance. My start relay is the type at 6:27 and it looks fine inside and tests 4.7ohms model QPR-4R7. Does this type of system have the start capacitor inside the compressor somewhere? Also does the resistance on that overload seem high to you (0.5ohms for model B58-125)? Also how can you tell what a normal ohm reading is for the overload? What else could make the compressor act like this...the thermostat? That's all that's in this wiring diagram.

[@pnp8849]

Seems 88/108 is fairly common with vintage refrigerators and freezers. I'm troubleshooting a 42+ year old Sears 106.6327150 upright freezer that went out for the first time last summer, and it has the same spec for the capacitor in it. I have yet to remove it from the plastic housing it's mounted in to see if it's leaked at all, but one afternoon this coming week I'll be going through it part by part in hopes that what made it go out was a still-available component. Lost 100+ lbs of salmon and beef when it went out last summer. Hooooo that stung the nostrils....

[@BigFarm_ah365]

I'm starting to thing my compressor may be mechanically stuck as I have replaced the relay/protector circuit, the run capacitor tested fine and all electrical readings on the compressor are exactly at spec from the datasheet. My condenser fan was making a loud racket, so I inspected and cleaned under the fridge from the front only, which stopped the noise, apparently by stopping the fan, because an hour or so later I noticed a puddle from the ice dispenser. The compressor was extremely warm. When I tested the protection circuit I got and am still getting .1 ohm, then 0, with 3 different meters and 2 sets of probes, so for $36 I replaced, but compressor still won't start(tested the new one also, reading didn't fluctuate). So, any ways to unstuck a compressor? I'm thinking about trying a heat gun, but this is not my area of expertise.

[@halledwardb]

So my Hisense Fridge has a NB1116HY Compressor, and it's pulling 10.5 amps after in rush current, then shuts off after 30 seconds. My guess is the PTC went bad, and the other Klixon is shutting it off after 30 seconds. I checked the compressor Ohm readings and it looked ok. 10uf cap is at 10.2 so that's fine. I've considered getting one of the cheap Megers to check compressors further, but it seems like I won't need it for this.

[@boashna]

anybody can answer this my system is same as 6:52 mark overload and ptc system if I am not sure if I use the correct ptc but I hear and see the overload activited and working. is that mean the ptc is correct and motor stuck .. what happens if ptc fits but wrong ..

[@01crazycooter]

On the Embraco app it cross-references compatible "best matches" of their new compressors when replacing an old obsolete Embraco compressors. When matching the specs some are almost identical but I did notice TSD starting device on some and PTC starting device on others. How would these be compatible without rearranging the terminals?

Hello I have a Hitachi Refrigerator/freezer, I recently had a power cut and my refrigerator stopped cooling , I was advised to change the relay .. and this relay is a 3 pin relay .. however I have gotten a 2 pin relay and a separate overload ... the motor started but cuts off about 30 seconds later .. so the freezer cools but doesnt ice up ,.. Does the difference in relay can create a problem

I have a relay model P6R8MD OR0702. On this one, there is no rattle at all, and when I check ohms, it's like 20-25, not 4.7 or 0 etc. When I check continuity, there is no beep, no continuity. On the refrigerator, the compressor never turns on, but the casing does get warm. The overload works and has continuity in the terminals. I assume the relay is bad, but I don't understand why the high ohms and no rattle. [update] I took the relay apart and the problem is that the disk is cracked but only a small part is chipped off. It didn't rattle because there is some kind of cardboard/plastic sleeve going around the disk, basically holding the shards together. I can't even get continuity directly from both sides of the disk. At least not from every touch point.

Does the Start Capacitor and Relay have any effect on the fridge freezer not shutting off?

Thank you for posting this very informative video,,,My question to you is what caused the compressor in my wine fridge to stop running and get very hot,,,Initially it stopped working and I replaced the overload protector(6750c-0004r) and start/run relay(PTC starter relay( P6R8MC) ,that didn't solve the problem so upon testing the thermostat I found it bad,so I got it to run after replacing the thermostat(18GLB020008) and that's when after running for awhile the compressor got very hot and I noticed a strange smell.,,I'm wondering if maybe it developed a refrigerant leak after moving things around like the condenser /evaporator,Thanks in advance
