England 25-pdvc/55-shp10 (adequate voltage reading needed)

[larryathey]

I'm new here as a member, but I've read a lot of posts here in the past, which is why I signed up here.

Long story short, my main board in my England 25-pdvc/55-shp10 died and I adapted it to run on a Raspberry Pi computer so I could control it from my cell phone.

I need somebody with a working unit with a stock main board to tell me if the ignitor is receiving 120 volts AC or if it's DC at a higher/equal voltage. I have full remote control of the stove from my phone, with the exception of the ignitor functioning correctly. I replaced it a year ago, so I wouldn't think that it has failed so soon. But, sending it 120 volts AC doesn't seem to be working.

As a side note. If others are interested in doing the same thing, I will be willing to make everything open-source. It's nothing but a $30 Raspberry Pi computer and 4 relays to control the two blowers and the two auger motors. It works like a charm, other than the auto-iginition at this point.

Overall greenhouse status.

I would imagine it is a 120v igniter , I believe that unit is rated at 300 watts .. have you tried to put an ohm meter on the leads and verify it isn’t burnt out?

Yes, but I don't have a reference for what its original resistance is supposed to be. I guess I could always buy another one, they're only $25 on Amazon. Based on the fact that they use a switching power supply on the original main board, it was a guessing game for me as to whether they were stepping up the voltage to it.

Looks like the PU-CHA igniter shows as 120v -300W .. so that answers that question lol

Maybe I do have one that went south in a year. That's only 2.5 amps and the relay I have turning it on/off is rated at 250 volts, 10 amps, so it's not the relay contacts breaking down...Amazon, here I come (again).
