Problem Adler Barbour Thermostat
I believe my thermostat is bad on my Adler Barbour refrigerator unit, should i replace with original or universal? How important is the U bend at the end of cap tube? Problem it runs continually, disconnect thermostat wire stops unit.
ANSWER
Only time I have seen a bad standard snap action thermostat is either the
knob shaft is frozen and can not be freed up with WD40 or small temperature sense tube is broken.
Adler Barbour calls for the last five inches of tube be bent into a U shape and
clamped under evaporator bracket provided. There are generally three
temperature ranges for refrigeration thermostats, Refrigerator, freezer and Cooler.
Thermostats used on thin plate evaporators like AB only sense evaporator
temperatures not box temperature other type’s sense box temperature. I prefer
the standard snap action thermostats for refrigerators as they are not easily damaged. I believe AB used a Danfoss thermostat with a temperature range of -13 to + 38 degrees F. To achieve correct temperature range at least 4+ inches at end of thermostat’s temperature sense tube must clamped under evaporator plate provided for this purpose.
