Product review (4 stars): Exact Replacement
for our GE Model# TBX18TMB, Mfg Date Oct 1990, top freezer refrigerator. My son replaced in 20 minutes. But this did not solve our problem. He checked the valve on rear of refrigerator with a voltmeter and it was out so I ordered a water valve, GE WR57X10033. We had our first row of ice cubes in two hours but we did not use the first bin to make sure the water line was clean and clear. About 12 hours for two bins. I like the cubes which are somewhat slimmer than the original much better. Works great!
