In the Event of Failure…
Trouble Shooting
Problem Possible Cause Solution
Earth leakage breaker failure Replace the part.
Power switch failure Replace the part.
The device does not start
when turning on the power
switch.
Power source failure
Connect to the appropriate
power source
Heater disconnection Replace the part.
SSR failure Replace the part. Temperature does not rise.
Temperature controller failure Replace the part.
Temperature sensor failure Replace the part.
Temperature controller failure Replace the part.
Clogging of condenser with dust Clean the fin on condenser
Much frost on evaporator Defrost
Relay failure Replace the part.
Power source failure
Connect to the appropriate
power source
Temperature does not fall.
Refrigerator failure Repair or replace the part.
SSR failure Replace the part. Heater does not stop working
when the temperature reaches
setting value.
Temperature controller failure Replace the part.
If power failure occurs…
The unit returns automatically to start operation automatically with the same condition as just
before the failure when it occurs during operation and is recovered. When I used a backup
power supply for blackout return, but a blackout occurred for need in less than 30 minutes more
than 30 minutes as for the charge time of the backup power supply since I turned on electricity
in a device, there is the thing that a blackout does not return temporarily. The blackout return
function operates normally after it was charged a backup power supply enough because I am not
abnormal.
