running of compressor may be likely to cause compressor burn-out.

Solution: Immediately have the compressor stop running; one hour later, i.e. after the compressor is moderately cooled down, adjust the temperature setting to a higher level to ensure that the compressor may stop running in 50 minutes; have the freezer operate at this temperature for 6~8 hours, and then decrease the temperature by -10℃; have the freezer operate at this temperature for 8 hours, and then decrease the temperature by -5~-10℃; in a word, decrease the temperature setting step by step until reaching the required temperature.

Serious compressor noise

Cause 1: It is normal that the noise level is higher than that of general home appliances and ultra-low temperature (ULT) freezers.

Check: It is normal only if the system noise is not higher than 75dB.

Solution: Do not use it in offices or laboratories where people stay for long.

Cause 2: Fan motor

Check: Check whether the noise is from compressor or fan motor.

The noise from compressor is for the fan motor’s efficiency reduces and fails to cool the compressor effectively.

Solution: Replace the fan motor

Cause 3: The compressor pressure increases due to dirty or clogged condenser lowering refrigeration effect.

Solution: Clean the condenser, and replace the compressor if necessary (serious damage).

Cause 4: Over-high room temperature

Over-high ambient temperature causes steep drop of refrigeration effect.

Solution: Adjust room temperature and check noise level. Over-high noise level indicates serious compressor damage, in which case the compressor must be replaced.

In case of any fault, be sure to immediately move the samples stored in the freezer into a proper device for safe preservation, and then turn off the freezer and contact Haier Headquarters or local After-sales Service Center to receive timely and fast service.
