20 Most Recent Therma-Stor Santa Fe Dehumidifier Questions & Answers


The dehumidifier should be removing water at 66F 70%rh.

First make sure that the compressor and fan are running. If they are, then turn the dehumidifier off and unplug the cord from the wall outlet. Next remove the front cover from the dehumidifier. Examine the evaporator coil (about 1/2 way up) beneath the plastic heat exchanger and above the stainless steel drain pan.

If the evaporator coil is cold and completely covered with frost & ice, the defrost thermostat may be defective. Replace the front cover. turn the humidity dial to "off". Plug the dehumidifier in to the wall outlet and set the fan switch to on - the fan will run (no compressor). Run this way for one hour to defrost the evaporator. Now adjust the humidity dial to your desired humidity and keep an eye on the dehumidifier. If it freezes up again and does not automatically defrost, the defrost thermostat should be replaced. Call the manufacturer at 1-800-533-7533 for parts and instructions.

If the evaporator coil is (mostly) warm and free of frost and ice, it is likely that some of the dehumidifier refrigerant has leaked out. this type of service should be done by a (refrigerant) certified technician. Call the manufacturer at 1-800-533-7533 for help with this service.

The classic model drains thru the clear hose using gravity. The drip pan in that unit is about 1/2 way up in the cabinet. Make sure the drain hose exits the unit and runs flat or downhill. If the drain hose is coiled vertically or run up hill causing water to trap within the hose it can cause water to back up in the dehumidifier drip pan and overflow causing your problem. If your drain is higher than the base of the dehumidifier, you can raise the dehumidifier or you can purchase a condensate pump kit that will allow the drain water to be pumped up to 15 feet above the dehumidifier.

The drain hose may have become disconnected from the drip pan as well. To check, turn off the humidistat to stop the dehumidifier from running. Next disconnect the cord from the power supply. Remove the six screws holding the cabinet side (with the label) from the cabinet and remove the cabinet side. The drain hose connects to a nipple on the bottom of the drip pan.

Contact Therma-Stor service for further inquiries at 1-800-533-7533 - they are located in the USA and are very helpful.

You will have to remove the plastic "cover" from the top of the unit to access the interior parts on the Advance model. Make sure you disconnect the power cord before beginning the disassembly. You can call the service group at 1-800-533-7533 to speak with a technician if you need help.

Hi Kevin,
If your dehumidifier is a Compact that is over 6-12 months old the problem may be a defective drain pan safety light switch. On the early units this waterproof switch wasn't as waterproff as the vendor described. A new "MORE" waterproof switch is now being used in that unit. The new switch is a direct replacement for the old switch. Please call the Thermastor Warranty Dept and they will send you a new switch at N/C. Their # is 800-533-7533 ext 8451 or contact Dwaine @ ext 8450.

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.

Windows is an operating system. It starts when the computer is turned on. How were you able to post this question if you do not know about any program on the computer? If you want to learn about windows they have cd-roms and books on how to use windows...I suggest you purchase one.

You posted in a dehumidifier forum. No one here will know about these loader issues. Perhaps re-post in another forum such as heavy equipment.

1: it isn't humid enough
2; it is running outside 40-95°F limits.
3. compressor isn't making the coils cold. It should be blowing warm air if it is working

Dehumidifiers | Answered on Sep 14, 2019


usually, owners manual defines error codes. Otherwise google "(make, model) error codes".
If it isn't blowing warm air, then the compressor isn't working which would be why it isn't making any water.
