Any appliance parts store will have the fan, just ask for 5 inch 5 blade GE fan from a fridge or freezer, you will have to enlarge the hole, but that's easy to do, I cut the hole just a tad smaller than it needs to be, then heat up the area that I want to slide it over and walla, usually under 7.00, oh and BTW, make sure you buy the one with the blades going the right way and install it so it blows over the fins. Your other option is a small oil cooler, in that case, just hand over your wallet to the parts store
As a guy who works in an appliance store, I will tell you that all the new cross references systems are model number dependent.
OGT, if you have a part number or a model number of one htat youve used in the past, that's be a big help... but if a customer walks in and just asks us for a 5" fan... it's not that I dont want to help... it's that I can't.
Kinda like car parts, gotta know what you're driving.
One of the most common failure fans for GE is the Evap Fan. The blade part number for a lot of them is WR60x114 (shown as 4.5" diam) but there are literally dozens of derivations.
Thanks for the great idea. (and the reminder about CW vs CCW)
