Haer in okieland
temps reach actual 110 degrees or more in the summer
. So garages are nice and toasty. Only thing I can recommend would be to semi-annually (about twice year) remove the back cover and the front vent cover and blow the dust bunnies out from the fan and coils. Dust build up reduces air flow and over time will cause you ref. and maybe freezer over heat (most freezers are sealed better with no visual vent opening) run hotter than normal and may cause it to stop cooling which would be the first thing I would check it that happens
.
