Hello Billy,
I have a small diagram on the panel on this heat/air system. I need a clear diagram or booklet showing the wiring of
all the components along with parts diagram to see if any are available. And yes I still need help with this as we will
need heat at our church. Thanks Abe

I think the toe stumper is the model number you have.

They have model, product numbers, manufacturing it possible for you to take a picture of the label on the furnace and post here using the attach files link?

Also what is the furnace doing or not doing?

Customer: replied 10 months ago.
I have a partial diagram off the door of the unit on the electrical part of it. I'll try to send it. Had to replace 24volt transformer,
can't get the heat contactor to pick up, reason for a better diagram.
Expert:  BillyHvac replied 10 months ago.

did you happen to check the limits on the heat cartridge face?

In an electric furnace you pretty much have line voltage sitting at the contactor for blower and elements and the 24v comes from thermostat and just runs through the limits.

Thats all there are for 24v safetys on this.

If you can load what you have I would appreciate it.

I have not received an answer to my question regarding a schematic or a print for the above HVAC unit.
I have repaired said unit using the partial diagram that I have. Would appreciate some feed back on this.
