Nice job explaining this. Makes sense that run to start would equal two common to run and start since resistors in series are equal to the total.

Great video. But the only thing this and other videos leave out is what happens if the sum of resistance readings DON'T add up. Meaning, what does that look like? I'm in that situation now, as a DIY trying to diagnose my compressor after replacing a bad 2-pole circuit breaker (one pole was bad) and finding the one of the terminal wires blown off which shorted to the casing and tripped the whole house power (ac cb's are on same outside meter panel as main shut off). Anyway, I get readings across all 3 pins, all under 10 ohms, but the C-S winding is reading high, thus the S-R sum doesn't match up with C-S+C-R. Frustrated. Waiting on new connector wire kit to arrive before I can hook it up and retry, but worried it might blow out again with this odd readings. I just don't know what typically happens in the field in this situation. No one seems to cover that part.

Great video but does that meter go to 1 M ohm? Just my understanding u require that scale to do the insulation test?

@kitwahlai236 3 ай бұрын

Very clear instructions. Thanks. Allow me a little comment, the running coil should be of higher ohm(thin wiring). Starting coil is thicker wiring and thus, lower ohms.

@harryschrysan3183 2 күн бұрын

You have those mixed The start has more turns and thinner wire and the run less turns and thicker wire. Run had less resistance to Start!

Common and run show a reading of .6 while the left side show 8.6. Making a total of 9 Which sounds good. But is that .6 reading maybe too low indicating a worn out compressor?

@mtbbiker6401 11 ай бұрын

Great video. thanks. If you have a ground short or OL when checking resistance, may the compressor still run or do you only perform these tests if the compressor won't run?

Relay checked good. I replaced the overtemp switch & relay; still won't work. Could the compressor be stuck? If so, how can I prove that? Thank you.

I can't find any videos on MECHANICAL FAILURES of a compressor. I have a compressor that the windings are fine but makes a ugly loud noise at start up and then trips the breaker. Anyone know of a good video to check for mechanical failures?

@JumpermanTech 2 жыл бұрын

I have many troubleshooting videos on my channel so subscribe for new videos every week! Sounds like locked rotor on the compressor. Check the compressor specs for LRA. Locked rotor amps. Upon startup, check amps on the compressor and if it's really high and matches the LRA versus the RLA (Running load amps) then you have locked rotor and the compressor needs to be replaced. Before determining that, make sure your start/run capacitors are good. If the caps are good, your compressor is bad and needs to be replaced. If the capacitors are bad, replace them and see what happens. Most likely will solve your issue. Thank me later 😅

@rocker8692 2 ай бұрын

I have a question,can you have all the winding check out good,but still inside the compressor it can be mechanically brokin inside?

@harryschrysan3183 2 күн бұрын

Yes, if it has lost oil the compressor can cease. The crankshaft can be fucked, reed valves can be broken (reed valves don't apply on scroll compressor).

So for a Samsung Compressor with the S-C-R scheme, I get readings of S-C 7.2 ohms, C-R 7.5 ohms, R-S 7.2 ohms but none went ground to copper. Is my compressor good or bad? One more note, the compressor- MKV190CL2B is label rated as 240VAC 3 P- Huh? I'm only providing residential from-the-wall 120VAC. How can it work?

@PuddinJr1993 3 ай бұрын

It is 3 phase, the 3 phase is created by a pulse width module signal from the inverter control board that converts single phase to 3 phase. In the Appliance tech world we see more dead inverters dead then compressors on Samsung units.

Unit ran for 1 second and would shut off . Got 50 amps when lra is 40. Chnaged cap , relay and tried a hard start. She wouldn't go. No high limit no lpco no continuity to ground... how would you finalize diagnostics. It would run when you bump started it as well but didn't seem to have too much power behind it .

in other videos it is said the Ohm's between the 3 should be more or less the same, instead of the top 2 = the bottom 2, why is that?

@harryschrysan3183 2 күн бұрын

What does top 2 does even mean? 😅 There is no such thing, you have to determine which is start and ran. Some times you can't read which one is which and have to find it yourself doing this test. Now for a single phase compressor the start winding has higher resistance between S and C, always! R to C has lower and the combination should equal to the two other findings. Small discrepancies like 0.5Ω to no more than 1Ω should be fine. Now, 3 phase motors should have ALL of their windings at the same resistance value. It's as simple as that. 🥂 Cheers

@louisdreyer7523 Жыл бұрын

Two types of shorts can occur in a compressor motor, a turn-to-turn short within a winding or a winding-to-frame short. The reading obtained between the Run and Common, and the Start and Common pins should be within .5 ohm of each other. If these readings are significantly different, the winding with the significantly lower reading has a turn-to-turn short and the compressor needs to be replaced. Check for a winding-to-the-motor- frame short by taking a reading between each of the pins and the compressor housing. If the meter's LCD displays anything other than an "O.L." during these tests, the compressor is bad and needs to be replaced.
