AJ, thanks for your reply. I cleaned the coils (1st time in 8 years) and have only heard the clicking noise cycle twice in the past three days and each time it only clicked two to three times. Presumably it is also clicking when I'm not in the kitchen to hear it. I think I bought some more time on the start relay. Is the relay part you recommend a Whirlpool/KitchenAid manufacturer part? Is this a direct replacement of the relay (with PTC) or does it include the start capacitor? I'm just looking ahead at how difficult the replacement would be.
By the way cleaning the wave-type coils on a KitchenAid side-by-side is difficult. Only the front section can be reached with a vacuum. Refrigerator coil cleaning brushes are useless. There isn't enough space to get to any coils beyond the 1st one. I used an air nozzle on the end of my compressor hose and blew it out while my wife held a vacuum. It cleaned ALL the coils completely, but does cause dust in the kitchen that has to be cleaned up. This is manageable. But I wasn't going to just clean the front coil and leave the 4-5 others clogged with dust. A shop VAC blowing air out should also work in place of the air compressor if folks don't have one..
