WHAT TO DO IF A FAULT OCCURS.
DO THE FOLLOWING
First, identify the symptoms of the fault by finding out if:
(a)
The refrigerator is too warm (above 8
0
C) and the compressor is NOT running.
You may determine if the compressor is running by:
-
Listening for the motor noise from the compressor
Or
-
Touching the compressor to see if it is vibrating
Or
-
Touching the compressor to see if it is warm.
(b)
The refrigerator is too warm (above 8
0
C) and the compressor is running at
times.
(c)
The refrigerator is too cold.
Next, do the CHECKS and ACTIONS, which correspond with the symptoms of the
fault you have found out above. These CHECKS and ACTIONS are explained in the
page of this manual. It is IMPORTANT that:
(a)
You be sure your choice of symptom is correct.
(b)
You always start with the first step listed on each page and proceed in order
through all the steps.
(c)
If, after doing ALL the CHECKS and ACTIONS the refrigerator is still not
working properly, you start at the beginning and check everything again.
(d)
If after checking all the faults twice, the refrigerator is still not working
properly, you move the vaccine into another refrigerator or a cold box and call the
technician immediately.
(e)
You note in the DAILY RECORD SHEET the CHECKS you made and the
ACTIONS taken. This will help the solar fridge technician to identify the fault with
your refrigerator.
