So a couple weeks ago, my fridge broke. Since I live in an apartment, the landlord had a new one brought up 3 flights of stairs by his crew. I saw an opportunity in this as it took those guys around 20 minutes to bring the new one up. I asked them if I could keep it and they said "sure go ahead." I now had this dead fridge out in my 30║ sun room that I needed to get working on. I already had a thermostat in my closet, but the closet has been proving too leaky to keep at a reasonable temp. So it worked out really well.
Here's what I did. (as usual, the pics should all link to their Flickr pages to see a larger version if you wish)
I went to home depot to get a soldering iron so I could start piecing this thing together with my old Honeywell classic mercury thermometer. On the clearance rack, there was a Honeywell non-programmable digital thermostat for $15 from $30. Score!
I proceeded to tear it apart so I could move the thermistor inside the fridge. If I had the option, I didn't want to have to open the fridge to check or change the temp.
Getting the thermistor off was easy, I had a hard time getting it back on as I had no way to remove the old solder so I couldn't get the leads through easily and when they did punch through, they took the solder pads with them. I also need more practice on smaller things, I'm used to soldering larger things like PA speakers and cables
After adding the jumper to the thermistor, I punched some holes in the fridge and ran the cable outside.
