WHile he was in his van I decided to Google the part - so I went downstairs and wrote down all the info on the box and came up and Googled it. The part was about $36. The guy came in from his van and gave me a quote of...$517 - that included his $89 fee I was going to have to pay anyways, a $46 fee to pick up the part, and the rest was the cost of the box and labor to install. I called my buddy Tim to see if I could handle this and he told me to just make sure I match up the wires and I should be fine. I declined the fix, paid the $89 and sent him on his way. I immediately got online and order the part for $36 + $21 shipping Fedex.
I got the part today and installed it in 30 minutes or so, in between putting Avi to bed and moving the camper out and showing Steve how to pop it up and attach it to his truck. The air conditioning is on now and working fine. This is the second piece of equipment I have fixed - I fixed the ignitor on our furnace last year when we had no heat - it was easy to do and shows if you have a little faith you can figure stuff out.
Next project I think is an attic fan - which will make my A/C unneeded!
