Re: how do I reset ?

It should come on automatically, if it does not then the thermal switch is faulty, and has to be replaced.

I have an Bionaire BPH1520 Micathermic Electric heater which will not heat up. I turned it off after use and now will not heat up when switched on. Digital display still lights up? Is there an internal...


The heater has a built in safety device which

will switch off the heater automatically in case

of accidental overheating. It can only resume

operation when the user has reset the unit. For the

BPH1520 (OH)will display in an overheat situation.

To reset the heater:

1. Unplug the heater and wait for 30 minutes

for the heater to cool down.

2. After the 30 minutes, plug the heater in

again and operate normally.

I have a electralog fireplace model #cs 3311. It doesn't stay on very long. Even if i turn the thermostat up it doesn't turn on

It's probably the Temperature Cut Off Switch. It turns the heater off if it's overheating. To reset the switch turn the Main On/Off Switch to OFF . Wait 5 minutes and turn it back ON.

If you need to continuously reset the heater, unplug the unit and call Dimplex North
America Limited at 1-800-668-6663.

Hope this helped to solve your problem.

How do I use the Delonghi trv0715 1500w Vento High speed convection heater

The owner's manual is available as a PDF here: .

Many recommend you plug the heater in and turn it on in a well-ventilated room (like a garage) for the few hours of use. If you are using the heater to warm a room, plug it in with the thermostat set to maximum and set the power selector to 3 until the room reaches the desired temperature. Then rotate the thermostat clockwise until you hear a click. You can set the power level to 1 or 2 to conserve energy while maintaining the current temperature settings.

If you are trying to avoid frozen pipes in an area, plug in the heater and set the power selector to 3 and thermostat to *.

Always remember to keep anything flammable away from the heater (loose drapes etc.) There is an overheating protection circuit built into the unit. To reset it, you need to call the DeLonghi service center.

I hope this helps.

Why does my dimplex model bf8000st fan and heat turn off after 2 or 3 minutes? the flame lights keep working, just no fan or heat.

"Resetting the Temperature Cutoff Switch

This unit is equipped with a thermostat which controls the temperature
of the room by turning the heater on and off. The heater is protected
with a safety device to prevent overheating. Should the heater
overheat, an automatic cut out will turn the heater off and it will not
come back on without being reset. It can be reset by switching the
Main On/Off Switch to off and waiting five (5) minutes before switching
the unit back on."

I need to reset my Delonghi radiator. it overheated

Unscrew the four screws holding the front faceplate on (two are on the bottom of the radiator). From the bottom end gently pry up the faceplate, it will stay attached at the top end near the temperature selector. Look inside and you will see a black bridge like piece of metal with a plastic and metal thing stuck to it's center with two wires leading into it. It's basically a connection that melts when high temperatures are reached, therefore it must be replaced (pictured). You can bypass this by prying the metal bridge out, removing the wires leads from the switch and connecting them using a wire nut. BE AWARE THAT THIS WILL OVERRIDE THE HIGH TEMPERATURE SHUT OFF MECHANISM, so don't use it for drying off your coat again._361.jpg
