My GE Water cooler stopped giving hot water. Ge techs trouble shot the problem over the phone and told me to get a new one, because the heater was not working anymore. I'll replace the heater myself if I can find a source for it. It's a GE PROFILE TRI-TEMPERATURE WATER DISPENSER with REFRESHMENT CHILLER. MODEL: GXCF25FBS. The part is not listed on the GE web site.
