Re: EuropAce EWC 3108 Wine Chiller - Seems like no temperature sensor input

Happy New Year:cheers:

Latest update:
I have replaced the C106M, and it does not have the same "click-on-click-off" sound every 5 seconds anymore. And the incandescent bulb connected in series...

Re: EuropAce EWC 3108 Wine Chiller - Seems like no temperature sensor input

So I replaced the PTC with a similar device extracted near incoming live input from another power board. Powered up and immediately a tiny spark is seen, and nothing else happened. Restored the...

Re: EuropAce EWC 3108 Wine Chiller - Seems like no temperature sensor input

I am powering up the solenoid directly for the test, so bc337 is not in scope.

I am thinking the inrush device cut off the power supply when too much current is drawn.. But I will replace it to...

Re: EuropAce EWC 3108 Wine Chiller - Seems like no temperature sensor input

*** Merry Christmas everyone :cheers: ***

I was ignorant about incandescent light bulb, thinking it only works with AC voltage in my previous post. I retested connecting the output to a 100W...

Re: EuropAce EWC 3108 Wine Chiller - Seems like no temperature sensor input

No, I don't have this part yet but will go buy some later.

I am focusing on the solenoid PCB to determine if this is good or bad. I found someone's description of this solenoid, SDF0.8 3/2:...

Re: EuropAce EWC 3108 Wine Chiller - Seems like no temperature sensor input

I think you meant incandescent (not in-condensed) light bulb. Yes, I have done that not it's not lighting up at all, see post #29.

I suspect there is a short circuit somewhere and the PTC is shut...

Re: EuropAce EWC 3108 Wine Chiller - Seems like no temperature sensor input

Update:
I have replaced the 2 capacitors, tested but same outcome - clicked on/off every 5 seconds. In fact in inserted my DMM on the 2 output connectors during the tests, and the reading is 0Vdc...

Re: EuropAce EWC 3108 Wine Chiller - Seems like no temperature sensor input

The other capacitor is a 50V 1uF, see attached pic on how they are mounted. And yes, I found a 50V 1uF and a 450V 10uF capacitors from some power PCBs. Will find time to replace them and test it...

Re: EuropAce EWC 3108 Wine Chiller - Seems like no temperature sensor input

Re: EuropAce EWC 3108 Wine Chiller - Seems like no temperature sensor input

I have checked most of the components, and nothing seems obviously faulty.. So I wired the relay to a 12Vdc supply, and the solenoid PCB with external 240Vac. The output is stable 280+ Vdc.

I then...

Re: EuropAce EWC 3108 Wine Chiller - Seems like no temperature sensor input

There are only 2 relays - 1 for compressor and 1 for solenoid. I am convinced that the clicking noise came from solenoid itself as I can feel the clicking-vibration when I put my finger on it.

I...

Re: EuropAce EWC 3108 Wine Chiller - Seems like no temperature sensor input

I have done some tests and learnt something new today:

Re: EuropAce EWC 3108 Wine Chiller - Seems like no temperature sensor input

Here's new update:
1) I have wired an on-off switch between Heat & COMP pins.
2) On powered up the relay starts to click-on but click-off immediately
3) This click-on click-off is repeating...

Re: EuropAce EWC 3108 Wine Chiller - Seems like no temperature sensor input

This is a dual evaporators chiller, and the solenoid has 1 input and 2 output to the respective evaporator. The relay to this solenoid is switched on by the C1815 transistor with input from the...

Re: EuropAce EWC 3108 Wine Chiller - Seems like no temperature sensor input

I can't find specs and more information about this solenoid beside just basic general functions a 3-way 2-terminal solenoid vale.

Anyone can give some insight of how I may "stimulate" the...

Re: EuropAce EWC 3108 Wine Chiller - Seems like no temperature sensor input

I traced the solenoid signal from main PCB back to the display/control PCB and found the voltage is 0Vac. So confirmed there is no signal at source to power up the solenoid valve!

Now trying hard...

Re: EuropAce EWC 3108 Wine Chiller - Seems like no temperature sensor input

Re: EuropAce EWC 3108 Wine Chiller - Seems like no temperature sensor input

I do not know what a optic sensor looks like.. what does it do and how to test it?
I attached all the 3 PCBs, please point it out if you see it, thank you.

Re: EuropAce EWC 3108 Wine Chiller - Seems like no temperature sensor input

Yes, there is a temperature sensor in each of the compartment. The left display/control PCB for the top and right display/control PCB for the bottom compartment. They both measured ~9K ohm at ~28C.

2) There is a...
