Controls & Switches
Wine Guardian Control Board MCB 39H0043-00
The Wine Guardian Control Board MCB (part 39H0043-00) is the genuine replacement main control board for all Wine Guardian cooling units manufactured after January 2020. It runs the unit's logic: temperature control, fan and compressor staging, and the display.
It is commonly ordered when a unit shows a dead or garbled display, components that no longer respond, or erratic behavior that persists after power supply and sensors check out. As an authorized Wine Guardian dealer, we supply genuine Wine Guardian parts; units built before January 2020 use a different board, so confirm your serial number before ordering.

FAQ
Frequently Asked Questions
Which units does the 39H0043-00 control board fit?
It fits all Wine Guardian cooling units manufactured after January 2020, across configurations. Units built earlier use a different board, so verify your unit's serial number before ordering.
How do I know the control board has failed?
Typical signs are a dead or garbled display with power confirmed, fans or compressor that never stage, or erratic behavior that persists after sensors check out. Cheaper faults can mimic a bad board, so confirm power and sensors first.
Can I replace the control board myself?
The swap is connector-for-connector with power disconnected, and our replacement video shows the process on a TTW unit. If you are not comfortable documenting and re-landing wiring inside line-voltage equipment, use a qualified technician.
Is this a genuine Wine Guardian part?
Yes. As an authorized Wine Guardian dealer we supply genuine Wine Guardian replacement parts sourced through the manufacturer.
Confirm Your Serial Number First
Send your model and serial number and our team will confirm this board fits your unit. Final fit and installation should be confirmed with official Wine Guardian documentation and a licensed HVAC professional or qualified contractor.
