Short thermal protector SIAM SI HE-420

Hello dear community: I tell you quickly: I have a refrigerator no frost SIAM IF HE-420 I bought it approx. 5 years (the few specifications of the motocompresor I leave them in photo) 2 weeks or so there was a storm (City of Santa Fe) that left me without light for 20 hours (from 2am to 10pm then came normally) to the other day at 9pm after having been absent for 2 hours (the dimension is because I live alone and would have felt the click if it had occurred before), I began to hear the click of the thermal of the ball, he did it several times (lapse of 2 minutes approx.) until I noticed and immediately unplugged it and leave it like that until the next day (I have been registered with refrigeration for 11 years, unfortunately I could never practice this job that I like so much, and in regards to refrigerators I never learned the non-frost) I measured the motocompressor with multimeter and here the first oddity for me, the pins with the classic triangle with the pin up and the two down (sorry for the description) in the one of arri the thermal was fixed while in the 2 below the relay ptc is also connected to this a 5uf capacitor; the oddity is that the reading of the engine gave me this way: pin up with left pin with 5 ohm resistance pin up with right pin 10 ohm and the 2 pins down 6 ohm?!? can be this?? as if the common should have been the one on the left but the protector is plugged into the top one !!! I measure if it has continuity with the housing and does not have it, buy everything new and replace it does exactly the same to me the motor compressor starts normally, without apparent noises, and in about 1 minute it cuts the thermal protector of the ball, during this period the protector is a little hot to the touch but not the motocompressor: With the amperometric clamp I measure the starter (LRA) and it gives me 7.8 amp (the label says up to 12.2 if you look at the photo, and does not specify the gear, but goes down to 4 amp which is the time it cuts (1 minute). Dear community, the question is whether I should look at the electronic board, I understand that apparently it would not send electricity to the motor but should not cut the protector or could be some other element that I do not know. I thank you in advance for any response and to the site that I read it from time to time and I learn even theoretically THANKS THANKS

You said you checked the coils and it's not grounded right? Did you control the capacitor? Regards

If Alberto is not open, nor is the compressor grounded, the capacitor along with the protector and the relay replace them, they are new.

Supposedly one of the coils is failing 5 + 10 = 15 no (6) I would have to see you given 15 approx. Like all those data are few. The sum would have to tell you given something higher it seems like 26, 28

That is what Claudio does not understand, if it is as decis (that a coil is failing) or if the connection can be so. That is to say that 10 ohm would be the sum of both although it is in another location, (instead of being below it is on the right)

Let's see, if for 5 years I worked correctly with those connections, it is that the problem is not there, if it started to fail after an electrical blackout, it is there where you have to start to distrust, it is recommended to unplug the appliances when the power is cut off . The subject of the order of the pins is not a rule; not necessarily the common one you will always see it above although it is normal that it is so. I would begin to suspect the compressor. Regards

Yes, it seems to me that there is the issue, as Claudio said above the values are low and it is likely that the compressor is starting to fail. THANK YOU for your input Alberto Greetings

Hello, if you did not connect the other way around and confused the pins, what is failing you is the machining of the compressor that is gripping or seizing as it is said and when braking activates the thermal to get out of doubts leave the thermal and connect a cable with terminals a terminal to the thermal and the other terminal to the pin of smaller Ohms that would be the one of march and when you plug it you make a bridge with a screwdriver well insulated with the other pin that is only bone between the two of below and would have to start if it has problems interns will skip the thermic again and you will have to replace compressor if it goes out well consider relay defective or improperly connected

If I connect it for about 6 seconds, use the engine to burn

I put the connection as it came from the factory. In any case, it seems to me that this is the subject because those values seemed strange to me, tomorrow I put together a cable with crocodiles and I try them out .. Very grateful to Alberto and David and Claudio who gave me the solution.

Hi I was looking at the picture carefully and I see that it is a compressor with R600 and whatever the mechanical or electrical problem of the coils you should change compressor then be careful with the gas depressurizes both high and low before approaching a torch to do some welding

I understand David, I'm going to take her to a service since I don't have the tools to do it, I really hoped it was something electric since since I bought it I take care of it a lot, I have it impeccable I don't understand what could have happened so that it break the engine, maybe the internal cables at home, greetings and thanks again
