Those fuses were a ripoff from Trane-- about $4.00, and I have never
seen them available anywhere but a Trane parts dist. A few years ago
they finally quit using them and went to the flat car type that are
about 50 cents. Also, can't see the stat from here, but the white wire
should probably go on W2, if there is one on the stat, rather than W1. I
had a call several years ago where a customer had installed a
programmable stat on a Trane HP himself during the winter and hooked
white to W!. I bet he was real pleased with himself at how much warmer
air it put out, but was probably baffled why his electric bill went up
instead of down. Anyway, first warm day, the A/C was running, but
blowing out air about room temp. The heat strips were running any time
the comp. was. Hooking the white to W2 fixed it.

Hmmmm,
Wait a minute, people ever read the manual and tunr off the system when
doing something like this? I just don't understand.
