Test K: Voltage Within Cutout Range but Refrigerator Cuts Out
Is
input
voltage within
specification?
Correct input voltage.
NO
Remove refrigerator from enclosure,
but keep a power supply (either AC
or DC) connected.
Make sure:
- Upper and lower vents are not
blocked.
- The refigeratgor is not overloaded
with hot items.
- The ambient operating temperature
is lower than 131°F (55° C).
- If DC power is not connected, a
minimum of 90 VAC is present
Measure input voltage.
- 12 VDC nominal inout voltage is
10.9 - 17.0 VDC.
- 24 VDC nominal input voltage is
23.8 - 31.5 VDC,120 VAC or
240 VAC.
