Question about Therma-Stor Santa Fe Dehumidifier
Your post says you have an RX but the picture shows a SantaFe Classic.
In either case the massive frost build up is caused by a defective defrost thermostat. PN 4021470 Parts Dept 800-533-7533 x 8451
The defrost thermostat has an internal set of electrical contacts that are designed to open up and turn the compressor off when frost or ice has accumulated on the tubing and the evaporator coil. If the contacts fail to open, the compressor keeps running and the frost and ice just keep accumulating until such time as the homeowner unplugs the unit or a sevice tech replaces the defrost t-stat.
