RTD Switch wiring
I'm not sure what I'm doing wrong but I can't get the switch to work. I've soldered everything up twice now on two separate switches thinking the I melted the first. When it's all hooked up I get the "Oral" error message on the PID. Bypassing the switch with my RTD works. Take a look and see if there is something obvious. Do I have the right resistor?
Can you please try the following, just to see if the switch is still working?
Attach your multimeter to pin 1 and 7 and check for continuity. If no continuity, change the switch position. Once you read continuity, measure between 2 & 8 and 3 & 9.
Change the switch position and do the same for 7 & 4, 8 & 5 and 9 & 6.
Let me know you findings…
I'll check tonight. I still have one more unused switch in case I messed this one up soldering.
Everything else appears to work as planned. I need to add the element to my kettle and then can get back to brewing.
I measured continuity between pins 1 thru 6 with 7,8, and 9. The readings look correct? Unless pin 8 is fried? Except there’s continuity between 2 and 8.
5-8 and 5-9 does not look right. 5-8 should have continuity and 5-9 should not. Worst case, take a new switch attach the wires without soldering and see if it works. It's easy to fry the switch when it gets too hot.
Thanks for all the help BTW. It's very much appreciated.
So pin 5 might be fried maybe. I'll get another switch and give it another shot. I'd like to find some push-on connectors for the switch pins to make this a whole lot easier. I'm not terrible at soldering, just out of practice I guess.
Anytime! Yeah, I hate soldering small stuff!
