Range Hood Repair
If your range vent hood is having problems, then this handy guide will help run you diagnose and hopefully repair the unit. So read on and I will go through the troubleshooting guide. But first I must remind you that before you do any troubleshooting or repairs you need to unplug your hood from any power source. If you fail to do so it could result in damage to your appliance or yourself.
What to do if your range vent hood fan isn’t working: If your light still comes on, but the fan doesn’t work you either have a faulty fan switch or a burned out fan motor. You can replace either part without removing the unit from the wall, but you will need to test each part to see which one is defective. Your fan switch should read 0 ohms when it is switched to the on position. If it does not, replace your switch. If it does read 0 ohms, you will need to replace the fan motor.
What to do if your range vent hood light doesn’t work: usually when the light doesn’t work it is because the light bulb has burned out. So first replace the bulb, and if that doesn’t solve the problem and your fan still works, either the lamp-socket or the light switch is faulty. You can also replace either of these parts without having to remove the vent hood.
If your range vent hood isn’t working at all you should check for a blown fuse or a tripped circuit breaker.
What to do if your range vent hood fan only runs at one speed: usually if the fan motor or fan switch is defective it will cause your fan to run at only one speed. You can also replace either part without removing the vent from the wall. You will again need to use your ohm meter to determine what part is faulty. The fan switch should read 0 ohms when switched to the on position, if it doesn’t, replace the switch. If it does read 0 ohms you will need to replace the fan motor.
What to do if the light dimmer doesn’t work: if your light dimmer isn’t working it is a pretty simple fix; just replace the light dimmer switch.
What to do if the fan circulates the air, but doesn’t go outside: actually there are certain types of units that are meant to just circulate air, not remove it. Here is how to determine if your range hood is one of those models. If your hood has vent openings near the front top, and if air blows through the vents, you have a circulating only range vent hood. If you check in the cabinet above the vent hood, and you see a metal duct leading away from the vent, you have a venting style vent hood.
In summary, I hope this troubleshooting guide for your range vent hood has helped you located and fix your problem. If you haven’t, you should contact a qualified service technician.
