Range master 50000 exhaust fan stopped working

search web --and check with local electrical shops for a replacement

Light and fan are two separate functions in your hood. The fan gets very greasy from the cooking. The grease doesn't act as a lubricant but as dirt. Remove the fan from the unit and check to see if the shaft is wiggling,or if it is seized. At this point you may need to replace motor. If it turns somewhat put a few drops of oil at the shaft, both ends if possible, and spin the fan by hand until it's loose. Replace back into hood and see what happens. Many times the bearings in these fans go dry and will not spin. GOOD LUCK FRIEND.

Did you have it professionally installed? I would suggest contacting the manufacturer to see if the issue is under warranty. You can find the support page here: http://www.lg.com/us/support-product/lg-LSVC302ST#

Why the heater is provided in the exaust fan?? I am not getting the problem.

test this steps and fix it. God bless you

1. No power to the range hood
Make sure there's power getting to the range hood. Check for a tripped circuit breaker or a blown fuse. Check the wall socket (unless the hood is hard wired) for power with a voltmeter or by plugging something else in.

2. Fan switch
If your range hood only has a fan and no light or any other features, it won't start with a broken fan switch. Replace the switch if found defective.

3. Fan motor
If your range hood only has a fan and no light or any other features, it won't start with a broken fan motor. Replace the motor if found defective.

User Control and Display Board If the range vent hood fan and light are not working the user control and display board may be defective. Check other causes before ordering this board.

You have 2 windings in the motor that create a magnetic field. A winding is simply a coil of wire an they do not touch. when applying the voltage (turning on the fan) the windings create the mag. field causing the rotor to turn, which then of course turns the fan blade. When these windings get weak it causes them to heat up due to the resistance in the circuit and you there for loose ur mag. field... Or if the rotor starts getting restricted it will also heat up the windings an cause the fan to stop.. Time for a new venta hood....

Hi ronio,

I'm Harvey the Master Plumber.

Your problem is: After the power went out your Zephyr hood lights and fan don't work at all. There is a faint glow on the digital display but the fan and lights don't respond to pressing the control buttons.

First check the circuit breaker. If OK then check the transformer in the unit. It's next to the fan motor. If no power on the high side then you have a loose or broken connection. If you have no power on the low side the you have a bad transformer. If OK then you have a bad control board.

Hi shealy,

I'm Harvey the Master Plumber.

Your problem is: This hood worked fine until a light bulb blew out. Put in a new light bulb, but the lights will not turn off. Is the light switch bad or is there a problem with the control panel? The fan still works fine but the lights will not turn off or adjust dim or bright.

You're on the right track. The light control switch needs replacing. You might try utilizing the Repair Directory to find a repairman. If you have the tools and ability just remember to turn off the electric first.

You are dealing with a bad light switch. If you have the tools and the talent go for it.
