What causes motor overload relays or circuit breakers to open on my Daikin WGZ030DW Chiller?
- DdanielkochAug 22, 2025
If the motor overload relays or circuit breakers open in your Daikin Chiller, it could be due to low voltage during high load (check for excessive line drop), defective or grounded wiring (replace the compressor-motor), loose power wiring (check and tighten connections), high condensing temperature (see corrective steps for high discharge pressure), a power line fault causing unbalanced voltage (check supply voltage and notify the power company), or high ambient temperature around the overload relay (provide ventilation).
