Good idea for future reference/troubleshooting. Thanks!

Agree; Any digital meter has a low enough impedance not to overload any digital or computer circuits. Mosfet circuits are very susceptible to damage from this, along with static discharge damage. Which, BTW, my replacement board was packaged in a antistatic bag. I think that was overkill. It...

Don't know why I didn't think of this earlier, but this unit for my shop is basically the same one on our house too. I toyed with the idea of using its parts for trouble shooting but didn't want to risk burning those up too and not have heat in the house! So, I took voltage readings of the...

Thanks Wuzzat?, Here's the diagram... You can see at the bottom how the "Remote Sparker Control" is apparently controlled by the "Ignition Control Board" at the top. It looks like it is continuously powered by 24VAC along with the the gas valve whenever heat is called for and the black and...

On my ICP HVAC unit, mod# PGF336080K00A1, I am getting gas flow to the burners but no spark at the electrodes. I am assuming that since the gas valve is opening, that means all the limit and rollout switches are working. I also have power coming out of the pressure switch. It seems that the...

I forgot to turn off the circuit breaker to my air compressor last night. Well, during the night it turned on, and at some point both connecting rods broke. Since it couldn't build pressure, it ran for who knows how long until I heard it running this morning. Is there a method or system...

When routing the romex in the attic, (Wood framing), what's the best way? Is it normal practice to just run it directly across from junction box to junction box or should the wiring be secured along the bottom of the trusses and then across to the next junction box? Should I drill 3/4" holes...
