Did you follow the wires to include all roll out switches?

Customer: replied 3 years ago.

Yep, placed all wires back on the receptical after replacing the new parts out.

There are quite a few limits on this model...did you check the blower limis?

See page 30 here


Customer: replied 3 years ago.

I can go take a look again, would these be in the blower casing on the blower or in the same case along with the other furnace components? Would these be a manual reset button as well or would they be required to be replaced?

Blower limits are generally manually reset.

Look at the diagram on page 30 and you can follow the blue wires...and I believe at some point it changes to orange. The switches are in series so just keep following the wires switch to switch

You sir can go buy yourself a steak dinner tonight. Now working was able to manually reset. Would you recommend that I buy a new part or would the manual reset be sufficient? I know it tripped from a bad air filter sometime back but this is the first time using the heat.

The reset is 100% fine with no need to replace.

I am very pleased you have heat.

Thank you for your assistance on your end.
