Holmes Products Recent Questions, Troubleshooting Help & Support

After spending hours searching for this supposed little hole easy to miss, I called customer service. I found out that it's easy to miss because it doesn't exist!

Here's the correct answer: Once you've replaced the filters, turn the unit back on. Then, with the machine running, press and hold down the on/off power button for about two seconds. The red light will flash and then turn off.

The fuse is usually in the plug, that you plug into wall socket. If you look at the plug, you should see a small, rectangular slot with a small tab at one end. Get a small screwdriver to slide it open. The fuse is in there.

Im looking for exactly the same thing. Any luck locating it?

Am I the only one reading that the OP is asking about a box fan.....never seen lights on a box fan...

I'm also trying to bypass the 3 speed knob on my box fan. Is it possible? I ask because preliminary testing of holding wires to each other turned the blade but began getting hot and with enough time I'm sure would've been a pretty nice fire.

Wiring diagram for a 3-way switch, one of the many wiring diagrams showing different methods of wiring a three way switch circuit. This electrical wiring diagram shows power into light switch Box #1 – wire to light from switch box #1, and from switch box #1 to three-way light switch box #2.

Probably the thermostat contacts have become worn and a certain amount of arcing is happening when they close. Replacement thermostat units used to be easy to change and were readily available for quality domestically manufactured oil filled radiators but these days it would probably be cheaper to buy an imported heater. You wouldn't lose by asking your local supplier and if they are still available check the internet price. It would be wise to check the wiring and internal connections before junking it.

The problem is most likely the over heating sensor thermostat located directly under the heating elements - The reason the over-heat safety thermostat sensor is tripping the warning buzzer is because either the cool air fan intake is obstructed with dust / dirt, or the fan motor stopped rotating, or the over-heating condition thermostat is defective, or over sensitive - Usually when the cool air intake is obstructed for any reason, the heating elements will glow brighter, and hotter without good air flow, and the elements may start to bow downwards closer to the over-heating safety thermostat - However, if the safety thermostat is defective, it can trigger the warning buzzer even though there may not be an over-heating condition / event present - The buzzer warning going off prematurely also occurred with my Holmes space heater - I checked the air flow first, and then the appliance tip-over switch second - Both were found functioning properly - It wasn't until I replaced the safety over-heating thermostat, did the buzzer stop going off moments after I plugged the space heater in an outlet.

You have a short. This is either from a bad cable or a faulty price of gear.

to find the problem do you want to isolate pieces of the system. Turn on just your speakers (if they're powered) or amps (if the speakers are not powered). With the mixer off, if you were getting a pause the short exists after the mixer. No buzz? Great! Turn the amps or speakers off to prevent popping. Turn on the mixer, and then turn on the speakers or amps. If you have a bus now with all channels on the mixer down it is likely your mixer. If there is no buzz, Bring the channels up one at a time. Once you find the buzz, turn the channel back down and plug unknown working microphone and cable into its channel. If the Mike buzzes when you bring the channel up it's the channel on the mixer. If it does not then the issue exists before the mixer. This is most likely and also the least expensive to resolve. Check the snake if you have one and all cables in line in a similar fashion. Most likely a snake channel has failed, you have a bad cable plugged in the snake Or you have a bad DI box or mic plugged in.

Happy hunting
