I've only been learning about refrigeration stuff for about a day so please bear with me.
My whirlpool fridge kicked the bucket a few days ago. The fan stays on but the compressor dies a few seconds after starting each time. It continues to cycle but same happens. Doesn't make any difference if I switch it off for a few hours. The compressor is not even heating up.
It has 2 model numbers on different stickers:
WRN28NWB6 and BG348W-Q-WPLAU
Compressor model: Samsung D162Q-L1Z
240v
Trouble is I've done all the tests that are written about on the web and I'm getting results that point to both compressor and PTC from my amateur interpretation.
The ground is ok on all three compressor terminals. The resistances don't add up though:
S-C 15.5 ohm
M-C 9.3 ohm
M-S 11.5 ohm
I presume M is run but even those numbers don't look right. The PTC attaches the bottom two pins which is marked M and S. From what I've read the highest resistance should be between those two.
The PTC measures about 30 ohms cold. I've opened it and the disc inside is intact and looks shiny and new. However I tried the lightbulb test. It took about 20-30 seconds before the light went out.
Possibly the way I wired it? I only had a 40w bulb in a lamp that I could cut the wires on. So to beef it up I hooked another lamp with 2 * 50w bulbs by attaching alligator clips to wires and then to the pins on 100w lamp plug. Had limited stuff so it was the best I could manage. It looks sorta like this:
L---|--40w----|
|--100w---|
|
PTC---N
Now I guess since the lamps are in parallel I'm not getting the 140w I was hoping for. But I'm not 100% sure on how to measure what it was. If I use the 40w lamp on it's own the light stays on (I stopped waiting after a few minutes).
Any pointers would be most welcome. I don't seem to able find much on the fridge model let alone parts. I'm a bit dubious about shelling out for a new PTC as those compressor reading are definitely way off the expected small + medium = big.
