Most gases used as refrigerants pose health risks
if inhaled. If you suspect a refrigerant leak, provide adequate
ventilation and contact a qualified service technician.
A refrigerant leak can cause a freezer
to fail to get cold enough; however, leaks are very uncommon.
Also, unlike some automobile air conditioners, it is never necessary
to "top off" the refrigerant. The refrigeration system
is a closed system and the addition of refrigerant is rarely called
for.
Never attempt to chip away ice in
your freezer. Even the slightest nick of the cooling coils can
result in a very expensive repair or even the total loss of your
appliance.
A refrigerant leak can be repaired
only by a qualified service technician. If you have ruled out
all other possible causes, have a technician inspect your freezer.
In theory, if you can locate the
leak, a cold weather epoxy seal could be used to patch the hole.
However, these patches will often fail after only a year or two.
Once a patch is made, then the system must be recharged with refrigerant.
Recharging the system can only be done by a qualified technician.
