When providing maintenance service to customers it is necessary to understand the function controlled by a micro computer thoroughly, so as not to mistakenly identify correct operations as mis-operations. It is also necessary to perform the following simple checks before conducting detailed checks or exchanging printed circuit board. Before exchanging Printed circuit board Claim call from the user Ascertain the nature of the claim. Unit did not cool, etc. ¡ Is the power on? ¡ Is the thermostat setting correct? (Not too high?) ¡ Is the unit in a timer operation? ¡ Does user understand function? etc. Ascertain the operation status. Is this nonsense claim? YES No Operate the unit. ¡ Explain the function of the unit to user. Does the trouble occur again? No No need for PCB change Check further the status when the trouble occured (such as the timer of occurence, power failures, thunder, use status of other electrical appliances, etc). Clarify the reason for the problem and explain it thoroughly to the user. YES Temporarily turn off the power source and turn it on again in about 1 min. and turn the unit on again. Does the trouble occur again? No No need for PCB change Microcomputer runaway due to power source conditions is a possible cause. YES Disconnect connectors and connect them again. Operate the unit again after confirming that the fuse and the varistor equipped on PCB does not burn out. Does the trouble occur again? YES Carry out checks according to detailed check process (See later page) 1-64 No No need for PCB change The cause is defective connector contact.
