Dual pressure switch
Also called DPS.
There is no refrigerant leakage
Doubt the low pressure setting!
The freezer is pumped down
If the low pressure range is set too low
When the compressor starts, the low pressure may be sucked and the low pressure switch may drop.
Even if the DIFF of the low voltage switch is low, the contact drops quickly.
The higher the RANGE and the DIFF, the less the compressor will heat.
Please see the video how to use ^^
