A range hood/stove vent hood above your stove needs to be cleaned and maintained to work properly. Constant heavy smoke and heavy usage can cause “venting” problems or other faults. Here are the common problems that can arise if the range hood is having issues. The tips and methods below will help you to fix your Range Hood to get it working like new without faults or problems.
Range Hood Troubleshooting: Common problems with a faulty range hood
1. No power to the range hood (No fan or lights).
2. Appliance light bulbs do not come on when switched to ON position.
3. Fan does not come on with ON switch.
4. Range hood fan does NOT clear smoke from area.
5. Range vent hood makes strange loud or humming noises.
CAUTION: Remember to remove power to the Range Hood when troubleshooting the components below. Flip the circuit breaker OFF or unplug the hood from the power outlet.
1. Range Hood Has No Power:
If the range hood has no power check for a breaker that might have tripped or a fuse that may be blown. The range hood may be plugged into an outlet, if so check to be sure it is plugged in and the outlet is working. If the hood is electrically hard wired, check with a multimeter to find the power fault.
2. Lights On Range Hood Do Not Illuminate:
If the lights on the range hood do not come on, check that the light bulbs are not burnt out. If the light bulbs are working, check the switch to be sure it is in working order. If the switch is faulty, replace the range hood light switch. Check the switch with a multimeter to be sure it is at fault before replacing. The control board (on some range hoods) may be the issue of “no lights” so test the board if applicable.
3. Fan Does Not Turn ON In Range Hood:
If the fan on the range hood does not come on, check that the fan switch is in working order. Use a meter to check the fan switch. If the fan switch is in working order, check the fan motor. Use a meter to find out if the range hood fan motor is faulty. If faulty, replace the motor with an OEM part to be sure of proper operation.
4. Range Hood Fan Does Not Clear Smoke (Air) From Area:
If you have turned the fan setting to HIGH and the air is not being cleared away up and into the vent, first check the filter that the air enters into to be sure it is not extremely clogged with grease. If this is the case, remove the filter and clean the range hood filter in hot soapy water with grease removing soap. If the filter is clean the other issue might be a grease blockage may be restricting the airflow. Check the duct with a flashlight to be sure the inside is not blocked. Another issue might be the fan motor and or fan blades may be thick with grease making it hard for it to suck the air outward. Clean and or replace the fan motor if found to be faulty after testing it with a meter.
5. Fan On Range Hood Makes Loud Or Humming Noises:
When a strange sound comes from the range hood fan, most of the time the fan is simply covered in grease and thus causing the noise. Clean the fan motor and fan blades. If the sound continues, be sure the fan is centered and not rubbing or chafing against the side of the duct thus causing the noises. The fan may have come loose and simply needs to be tightened to be centered and stop the noise. Bent fan blades may also cause the rubbing noise, bend the fan blades to recenter the fan blades and stop the noise. If the noise continues, the fan motor may be faulty and needs to be tested and replaced.
