keep a spare set of fuses too!
another handy thing is to keep a couple of spare fuses habdy.
One day this week when I got home my air conditioner wasn't working.
I changed the fuses loceted behind the panel - where the original poster shows the on off connection.
Luckily for me it wasn't a Sunday night before a three day weekend.
I was able to get some at Hm Dpt but from now on I'm going to keep a new package (only $3.50 for two) in the garage.
