V-Guard Fridge Stabilizer Deluxe 50 - Dead - No Input & output LED lights up. No output voltage.
Condition
: Dead. No input or output LED light up.
Used
a pre-programmed IC CTM1273 to control the circuit board PWB.
On
checking, the thermal fuse found damaged.
Replaced the thermal fuse (inserted inside the primary side of the transformer).
Power light came alive, but there was no output LED light up; or any
output voltage; even after 5 minute duration.
Checked
the components on circuit board. The
relay used (on board) HJR-3FF-S-2 was found not working. It's winding was open. Replaced the same; and checked OK.
When
checking this stabilizer, please check the AC fuse [the thermal fuse in the
transformer] first; then the Relay. This fuse can be
replaced. Pull that fuse out (after de-solder its two connections). Insert a new one in place and solder the
terminals as it was. I’ve marked both
the damaged component that I’ve replaced.
Note the photographs attached.
If
the pre-programmed IC said above is found damaged, contact the authorized
service center for V-Guard. There is no
way to get it from open electronic spare part market.
