    I had this same problem, shuts off after about a minute running on high heat. I cleaned the small intake slots on the top rear, they were plugged with dust mites. Now the heater works fine on high heat. Seems the over temp sensor needs air flow, or it opens and shuts down the unit. Then I had to unplug the heater and wait 15 minutes for the sensor to reset. Fixed now!

If you have the same heater i do then in between the elements at the bottom there is a safety swith that bends when it heats up and breaks the connection Dont mess with it plugged in it will shock the hell out of you but if you bend it down it wont be able to lift off the circut and will stay running untill you turn it off

    I have the same Sunbeam quartz heater that would stop working after running fine on level 2 for a few minutes. I tried your fix (bending down the switch metal) and it worked.

    It is probably the top vents clogged with dust mites not allowing air to circulate to the over temp sensor. Clean with small screwdriver and vacuum out, then blow out with canned air.

SOURCE: I have a lasko tower ceramic heater that keeps shutting down.

mine does the same thing every year. I just clean out the dust from the vents on the back of the heater so the heater can breath otherwise it could get too hot and the safety fetcher kick in and makes the heater stop working.

SOURCE: Bionaire BH3950 Does not heat

I'm not an expert, but I have two of these units that are working fine.

The on/off switch (the top switch) has a light in it that illuminates when the heater is on and heating. If this light comes on and there is no heat, then the element is probably burned out.

The heater has a safety switch that prevents the unit from working if it is not upright. If the heater was stored for any length of time on its side, the safety switch might have stuck in the off position. Unplug the heater and with the heater upright, try shaking it or slapping it firmly with your hand to se if this fixes the problem.

If none of this works, then as sunmasc says, the thermostat is bad.

SOURCE: troubleshooting reddy heater 115,000btu

If a drop of water passes through the system and causes a momentary flameout condition, the photocell tells the control board to shut down- and it does. The photocell has done it's job. The ignitor only gets red for the first 5 seconds of burn-time, then the flame keeps itself going, at least until the water passes. Since water doesn't burn the flame goes out and there is nothing to restart the flame.

SOURCE: electric furnace/heater pump/fan unit won't shut off

There are dip switches on the main board.. When you remove the lower panel on the air handler there are instructions to where the dip switches should be for your units fan control. if the switches are in the correct configuration.. The Thermostat may be malfunctioning or not wired properly. and last.. and most expensive.. the motherboard may also be failing.

It's only normal, if the heater reached the temperature level you have it set on. More than likely, the heater over heat switch shut the heater down. If that's the case, the heating element may simply need cleaning.

You can accomplish this by turning the unit OFF & Unplugging it. The heater element is under the stove and can be cleaned with a vacuum that has a hose and brush attachment. Even a crevice tool will help. The heaters over a short period of time, can get clogged with dust, lint, pet hair, etc. Keeping them clean will lengthen the longevity of the heater.

Hope this helps you. Please let me know.

How does the themostate settings on this heater of 1 and 2 affect the heat output?

I just did a search, and I learned that your heater has two settings-- two different levels of heatT

Power 1,500 - 1,000 Watt

So-- likely position #1 will be 1,000 watts, and #2 will be the greater number: 1,500 watts.

Just doing the Math, the 1,000 watt setting will use 2/3rds of the amount of electricity, (and thus put out 1/3rd less heat!)-- compared with the 1,500 watt setting.

If you have to run this heater on an extension cord (NOT RECOMMENDED I might add!)-- the lower wattage would be the safer, and more efficient setting.

I hope this helps-

My patton prh11 heater keeps acting like its going to come on for maybe about a minute or so and then actually comes on. It just keeps turning on and off constantly. Maybe about 15 times in a minute.

These heaters all have safety devises in them some for tip over and all for over heating. Your problem sounds as if it has a bad over heating sensor. These will have two wires one in one out, it is usually a positive wire. When they sense that the heater is to hot it shuts it down upon cooling it allows the heater to turn back on. The tip switch does the same if upright it turns on if tipped it turns it off. They are mechanical and thermal switches and they do go bad. These can be jumped out to trouble shoot the problem but I would not run it with out these safety devices in it.

Sunbeam SLP3310-UM shuts off after 2 minutes. I unplug it and hear a relay clicking after a couple of minutes. Replug it, and shuts off again after 2 minutes. It worked fine last year, not this year.

It's broken --- call Sunbeam customer service (888) 264-9669 and have your receipt and serial number ready. They are aware that these have faulty switches in them.

Sunbeam Electric Blanket Model 972 A5 Type 692 (or 592) with temperature control 1 to 9 with 75 mins and 12 hrs and off control positions. The light blinks red and the blanket won't heat up. Please...

Did you get helped last year? If so please ignore. Otherwise....

Hi. You can locate a Sunbeam Service Centre via

You're looking at $69,95 recommended retail.

BTW have you checked that it's not the blanket? Swap the controls over, if the problem follows the control it's the control. If the problem stays on the same side of the blanket, it's the blanket.

Also note Sunbeam has a 3 year warranty on electric blankets. If Date Of Purchase is less than 3 years ago call 1800025059 option 1 to speak to their Customer Service,
