Hello

Expert:  Billy replied 1 year ago.
Did you follow the wires to include all roll out switches?

Customer: replied 1 year ago.

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

Expert:  Billy replied 1 year ago.
There are quite a few limits on this model...did you check the blower limis?

See page 30 here

Customer: replied 1 year 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?

Expert:  Billy replied 1 year ago.
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

Customer: replied 1 year ago.

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.

Expert:  Billy replied 1 year ago.

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.
