Troubleshooting and Repair Process for Non-Cooling 389 21 Yamada Water Dispenser
Today, we will delve into troubleshooting an issue with a water dispenser that is not cooling, with the additional problem of the cold water light blinking frequently. Typically, this situation arises due to a circuit board malfunction, which could be caused by burnt or damaged components on the board.
Firstly, we remove the rear filters and open the back cover of the water dispenser to access the circuit board for inspection and repair. Despite the apparent issue, we start with the basics, checking each component on the circuit board one by one, including fuses and other vulnerable components, for any signs of short circuits or damage. Upon testing, we find that one of the capacitors is swollen, which likely resulted in the cooling function failure.
We proceed to replace the capacitor with a new one that has higher parameters and stronger voltage resistance to better suit the water dispenser's requirements. After the replacement, we retest and confirm that the cooling plate and fan are operating correctly, and the temperature of the cold water begins to decrease.
Finally, we reinstall the circuit board into the water dispenser, replace the filters, and close the cover, completing the repair process smoothly. If you encounter issues with your water dispenser not cooling, feel free to contact us at Captain Specialist Water Filter, and we will do our utmost to resolve the problem.
