Possible cause
Ways to fix it
- check the voltage in the grid;
- check the state of the power cable and the
connection;
- check fuse F1 in the fuse box of the power
box;
- fix the problems in the power supply line.
- avoiding loading warm items into the box and
reduce the number of times the door is opened;
- melt the evaporator using forced melting;
- reduce the interval between melting runs;
- check the sealing of the doors and the seams
between panels, fix the sealing of the doors and
cover the seams between panels with sealer
cement.
- The unit must not be operated in environment
temperatures of more than 32С;
- check air access through the condenser, if
necessary, blow air through it;
- ensure there is a gap of 400 to 600 mm
between the fan mesh and the ceiling;
- check the condenser fan and fix any problems
you may find with it;
- find and fix the freon leak, if there is a
suspected freon leak the unit must not be
operated because a freon leak can cause the
compressor to break down.
