Build a green house or a picnic bench

If you get all the wiring replaced keep the aluminum wire and take it to a recycle center. Aluminum is worth a decent amount of cash if your up to it.

Lorne is right on that about using a good primer even if you don't spend a lot on the paint primer is of up most importance. I would recomend Kwall or valspar on paint if you can afford it if not you can get color palace from walmart which is made by Sherman Williams.

I will go ahead and replace them all. And im not going to leave the site its like a library to me =). Im sure i will be looking for more help on something else. I may also be able to help out someone else.

I pulled the blower unit out and that little plate on the bottom was flipped around so i took it out and fliped it the other way and it works just fine. The fan wasnt flow...

OK i havent dont this before ill look and see. Any hints or tips on this other than make sure power and gas are off.?

Yeah i will try and back trace it today.

ok I will do that today and try and back track it.

I replaced the lower limit switch with the same one new and still doing the same thing. Also the t stat dosent stop the call for heat unitl the right temp is reached. I turned the furnace on and used my temp gun and the air coming out of the vent reached a temp of about 104. then the exchanger shuts...

well i jumpered it like you said and the exchanger heated up fan kicked on and i heard that limit switch click but with the jumper wire in there it ran like it did before i cleaned the blower out.

yeah i hear a click and the signal to the valve goes to 0 the click is coming from lower limit switch.
