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

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.

Is it an old model? Should you try to have it replaced?

To reboot unplug the unit for 30 minutes. then plug back in. This may fix the problem, and try this link for troubleshooting PDF.http://homeappliance.manualsonline.com/manuals/mfg/bionaire/127176.html...

Hi,
The only way to tell for sure what is wrong would be to use an electrical meter and troubleshoot all of the switches, the thermostat and the heating elements... If you do not use a meter and find out exactly what the problem is then you run the risk of buying parts that you do not need.
Find someone that can hands on go through the circuitry and find the exact cause of the problem.

Same problem, I took it apart and found that the thermostat had failed, there are "points" burnt out (like in older cars distributors) that make contact at the thermostat and there were some solder joints which had come loose as well, adding up to no contact through the "hot" side of the wiring. Basically it's not something you can repair, just go buy a new heater, they're about $30. If you decide to try to fix it, beware, it might be dangerous if you don't do everything exactly right, also beware that parts might cost more than the heater.

Hello- These heaters have been recalled.The Holmes heater company will mail you a new free heater, if u mail them back your power cord. Please check the recall website. Julie :)

check your fuses, may have blown the heat side. If fuses are good, and still no heat? replace the unit.
