Thanks Samurai. Do you have any material on how to troubleshoot these dual and triple infinite Switches?

So with the cold water valve failed open, there would be no load current to keep the triac turned on, and therefore i would get 0 VAC between VCH7.1 to VCH7.3. I totally got it. Thanks for the clarification Samurai.

Good job, Mike. This shows that you have learned a lot of the principles that you need to know in order to decipher any schematic. You already know more than the majority of techs out there (we know – we have been dealing with them for years!). Our courses are about teaching principles and giving a few examples to help. As you go out there and apply these principles to the schematics you encounter (both in real life and online – in our webinars and YouTube videos), you’ll continue to grow in proficiency.

Thanks Susan. I’m pretty I’m no where as experienced as most people in this industry. Still got a lot to learn. Thanks for your encouragement.

Ok i took notes of what you have said above and going back and relearn. Thank you.

Give me the time stamp on the video where you saw this so I can jump to it and review. I make so many videos, I don’t remember them all in detail and don’t have time to re-watch them in their

It’s between minute 30:10 – 31:20. Thanks in advance Samurai.

1. Line voltage is directly supplying the drain pump.
2. My best answer is that the cold water valve will not open if both triacs were closed because it would create a shunt, bypassing the cold water because the resistance on that Drain Pump is much lower than that of the water valve.
3. The triacs are controlled by a MICOM which sends DC current to the triacs in order to open the triacs gate, which in turn will allow AC current to flow through the triacs. Load current also is needed to keep the triacs turn on.
4. If the same voltage is applied to both sides of a load it would trip the circuit breaker and it’s called a short. ( Return current has to be 0v or else it would trip the circuit breaker)
5. The water valve uses the drain pump neutral as its return path. The drain pump would not run in this situation because most of the voltage is dropped across the water valve load and there won’t be voltage for the drain pump to run on.
6. The voltage drop across 2 loads in a series circuit is proportional it each load’s resistance.
7. Load 1 Voltage drop is 115 VAC, Load 2 Voltage drop is 4.6 VAC. Only 1 load will be able to run in this configuration.
8. If the drain pump winding fails open, in this case the cold and hot water valve would not work because it’s missing neutral. So problems such as no fill, or no drain.
9. This way if the drain pump failed electrically, water valve would not work.
10. I will use LoWz function.

After watching the video again, my only question is that if the cold water valve were to fail instead of the drain pump, why would you measure 0 VAC between VCH7.1 to VCH7.3? I thought i should measure 120vac because the cold valve circuit is open and there should not be any voltage present at VCH7.3. I got why i should get 0VAC between VCH7.1 to VCH7.3 if the drain pump failed because now I got an open neutral but line voltage is still present at VCH7.3 all the way up to DP2.2.

Sorry noob question again.

and the other 2 black bare wires they go to line and neutral.

OK no problem. I got a question about this product right here that Scott recommended. It’s the Sealed Unit Parts URO41 OV 1/4-1/3 115V Relay. It’s got 2 wire harness connector for the red and white wires, which are meant for relay capacitor. What if I ran into a relay without a capacitor but only an overload? Do i just leave those wire harness connector be and connect the red, white and black to the corresponding winding on the compressor, Right?

Oh got it. Thanks man

[Dean B]

Cool THanks

[Dean B]

got it

[Dean B]

I saw Scott makes his own cheater cord with alligator clips and all them fancy stuff. How do i make one just like that? It’s super handy i think.

[Dean B]

Is there a video online somewhere to show how to use these URO and URPO devices. I’ve never used them before. Thanks

[Dean B]

I’m aware of their differences. But how do i identify them, like what do those solenoid gas valve look like?

[Dean B]

So what’ts the difference between the “Surf Ind Light” and “Hot Ind Light”? And what is the purpose of contact L1-P?

[Dean B]

Wait a minute. So i can replace the cheater cord with one of these starting device that i can buy?
