I'm not sure why the repeatedly cryptic riddles, but I don't understand them. I did *every* single thing that people, including you suggested. I answered *every* single question that people, including you, asked. The compressor only went on twice out of a few dozen tries, after the hard-start cap. Either the hard-start cap 'went bad', or something else is wrong. I left no stone unturned that was suggested and no question unanswered that was asked. Not one. So you can remain cryptic with riddles or you can ask a simple question or suggest a test - but the cryptic riddles you're repeating are not useful in and of themselves, except to amuse you but they don't amuse me. I do realize I'm asking you for help, but I'm asking you to stop with the riddles becuase I don't understand the puzzles you are purposefully proposing. If you *really* wanted me to answer a question, you'd simply ask it instead of providing riddle (after riddle after riddle). I mean, how hard can your question be? I answered *EVERYTHING* asked of me. I tried *EVERYTHING* suggested. I can't be any more blunt (and I don't do riddles). No more riddles please. Just straight talk. 1. What is your question? 2. What is your suggestion? |

Sounds just exactly like a bad start relay on the compressor. This is considered "sealed system". If you have the owners manual, see how long is the sealed system warranty. Probably five years, so you're out of warranty. If it's out of warranty, are you any good with electrical repairs?

When you run into a problem, you can either do things differently, or force harder, using the technique which has failed up to that point. I offered you (repeatedly) a chance to do differently, and you ignored me repeatedly. This post is an example of trying to force your failing techniques even harder, and trying to force me to participate with your failings. I'll have you know, that I viewed NONE of the links, and barely read your text. By way of references, I've been working on domstic refrigerators for over 10 years. I'm fairly sure that if you'd done what I said, it would have been fixed several days ago.

The classic symptom is the computer comes on when hot. Look at the larger capacitors that have leads going through the board. If the top of them is rounded off like a dome they are bad. They should be flat. This could be on the motherboard or video board. --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus |

Put an oscilloscope on all the power supply lines and see if they look good. A typical voltmeter won't always see the problem. You can read 5V on the voltmeter and have horrible spikes on the line. Don't forget 5VSB. I've had several systems where the cap on the 5V standby supply went. Nothing else would run without it. |

I'll certainly give it a try first thing tomorrow, Phil. But I'm not optimistic given this confident pronouncement which I quote from the datasheet: "Typically, no capacitors are needed unless the device is situated more than 6 inches from the input filter capacitors, in which case an input bypass is needed. An optional output capacitor can be added to improve transient response. The adjustment terminal can be bypassed to achieve very high ripple rejection ratios that are difficult to achieve with standard 3-terminal regulators." So the manufacturers don't seem to think it's of any great importance at all. BTW, on the input side, the filter capacitor is less than one inch from the the reg's Vin terminal. |

IMO, The problem isn't so much the omission from the LM317 datasheet, it's more an omission from the NE555 one. Interestingly the ICM7555 datasheet says: "The ICM7555 and ICM7556 devices are, in most instances, direct replacements for the SE/NE 555/556 devices. However, it is possible to effect economies in the external component count using the ICM7555 and ICM7556. Because the bipolar SE/NE 555/556 devices produce large crowbar currents in the output driver, it is necessary to decouple the power supply lines with a good capacitor close to the device. The ICM7555 and ICM7556 devices produce no such transients" |

Any suggestions? > TIA. You may have two problems.. One, the timer is pulsing and thus causing a load variation. two, the 317 is a monolithic device and is sensitive to RF, meaning it can actually act as a detector in a sense.. of course, oscillatiion is common with these things, hence the need for caps. You should have a good storage cap on the output to handle riples from the load and also use some low inductive small caps across the electrolytic, input side and ref pin. ~50 uf for the load cap and maybe .1uf ceramic caps or the like for the RF snub. make sure you put a .1uf in parallel with the 50 or more uf cap.

Yeah, there's not much headroom for sure. I'd sooner have used a LM317AHVT but I don't have any 'in stock' here - but that's what I'd have used if I'd had one. |

I used the DC amp once, it worked.. put the meter away, next day used it again. As soon as I select DC amps now, it shows a -32 Amp offset. I can zero it however, It looks like the value its reporting is ~ 50% of the actual value. I have not used this meter for nothing else yet, but I did plug in the test leads to check to make sure the rest of the meter worked after seeing this, and it seems to work ok on the other funtions..

I considered trying to demagnetize it, but fear the voltages induced by the attempt might bust something, so I just use the zero function. It takes a very small magnetic field to disrupt the zero. Unless the initial offset is 0.0, you have to zero it anyway. I contacted the vendor and they said, "push the zero button." I once had a DC clamp probe that zeroed itself every time you opened the jaws. Nice feature. |
