SOURCE: My LG refrigerator has a blown fuse on the circuit

Yes. This fuse is replaceable, but, you will heed to De-solder the contacts, in order to remove the damaged fuse. this can be very challenging. If you are not an avid user of a soldering iron, i would just simply replace the board. If the soldering is not done correctly, this will cause the board to short, causing a spark.

I would , also, verify that the fuse is available for a non technician to purchase. Most vital components will not be available for purchase, if the purchaser is not a certified tech.

Is there a fuse for lg 50pw350

Fault with the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time; especially to Plasma TVs.

On a LG LSC26905TT need circuit board location to replace fuse

How do you know the fuse has blown if you haven't accessed the board? Check the mains incoming power first, and power to the compressor. The pcb is usually in the top above the door frame.

My LG wired remote control has no display - just turned off - seems to have no power - circuit breaker has not tripped? Any advice????

sounds like blown fuse in low voltage control wires. Due to short in wireing usually a wire rubbing against somthing due to vibration. Coating starts coming off wire then touches metal. If fuse replaced and it runs it will most likely will happen again unless short is located.

We have a King Pellet Stove 1 year old. Fuses keep blowing. Have replaced ignitor and fuses several time. Is a surge protector the answer or is it the circuit board? Thanks!

Please understand the reason for fuses blown:
1. High amphs of the main part in the unit. 2. Short circuit 3. Loose wiring. 3. Wire contacts corroded due to rusted or dusty.

Machine does not turn on but circuit board has power I think prob is circuit board

I would bet you have a duct fuse blown due to some sort of air flow restriction. Most duct fuses have small wires, do not carry a heat load, and are in the same circuit as the door switch. When drum temp rapidly rises to 350f the duct fuse melts and stops the appliance before dangerous situations occur.

I have an LG WM2277HW washing machine. My wife went in this morning to do some laundry and the thing is completely dead. No lights or signs of life. I checked the house circuit and the power to the...

Make sure the noise filter connectors are clean and connected properly. Get yourself a multimeter and check the voltage both on the load side and line side of the noise filter. It should read the same at 120VAC. The noise filter is the board before the main board. Replace it if the voltages on its load and line side are not the same.

The main board is not serviceable and must be replaced if faulty. It has a fuse and if it is blown, the main board is probably faulty. Look at the two brown capacitors on the top left of the main board. Next to it is a heat sink and to its right is a white "fuse-like" component with silver ends. That is the main board fuse. If it is blown, disconnect all the connectors from the main board except the one connecting it to the noise filter. Jump a single thin strand of wire in place of the fuse and apply power to the machine. Check if the power LED indicator on the main board lights up. If it does not, the main board is dead, replace it.

Please do not hesitate to update me about your findings above for further guidance if necessary.

LG Washer wont start, no power

Make sure there's power getting to the washer. Check for a tripped circuit breaker or a blown fuse. Check the wall socket for power. Sometimes the power cord disconnects at the washer, if this is the case, the wiring must be repaired or replaced.

37 inch LG LCD won't turn on due to power failure

Power failures can cause all types of problems, have you firstly checked the fuse in the mains plug? If that is ok then it may have blown an internal fuse in the power supply board, these are there to protect the rest of the circuit from power surges.
