Frequently Asked Questions

Q: Is this thermostat compatible with my refrigerator model?

A: This mechanical temperature control switch is a direct replacement for units that originally use the WDF28C-L-EX or WDFE32F thermostat. To confirm compatibility, locate the model number printed on your existing thermostat (usually on a label on the body of the switch) and compare it to these part numbers before purchasing.

Q: How difficult is it to install this refrigerator thermostat?

A: Installation is generally straightforward for a confident DIYer. The process typically involves disconnecting the old thermostat's wiring terminals, removing the capillary tube from the evaporator, fitting the new unit in its place, and reconnecting the terminals. Always unplug your refrigerator from the mains before beginning any repair work.

Q: What does a mechanical thermostat do in a refrigerator?

A: A mechanical (capillary) thermostat senses the cabinet temperature via a gas-filled sensing tube and automatically switches the compressor on or off to maintain your set temperature range. When the thermostat fails, the fridge may run continuously, not cool at all, or freeze items unexpectedly — replacing it restores normal operation.

Q: Where is this product made?

A: This thermostat is made in Mainland China.
