Re: How do you clean with a heating element?

It has to be taken apart and you need to blow compressed air through the front. dust particles get trapped between the fan and the heater element.

Why does the4 heater go through thermocouples

Check to see if the machine has a fan. If so, clean the blades real good with alcohol and QTips. Also while inside check to see if the vents on the heater elements are clean. If it's stopped up, air cannot circulate thru the heater properly causing heat to build up in the unit thereby causing thermocouple failure prematurely.

Bionaire BCH9212 does not produce heat

These Bionaires (including your 9212 and its taller version, the 9224) have a small temperature safety relay mounted slightly above the ceramic heating elements. Its purpose it to shut off the elements if they overheat, which I would assume would happen if the fan stops working or possibly if the outlet to the front becomes blocked (and these ceramic elements, which are like a radiator core, do get a lot of dust accumulated on the inside which will block air flow). The sensor is a small unit with exposed contacts and if these contacts open (driven by the temperature sensor connected to them) or if these contacts do not have good contact (say by dirt or oxidation build up that makes them effectively fully or partially open) then the ceramic elements will not work. My best suggestion to explain your problem is that the contacts on that safety switch became dirty during storage. The only way to verify that (and possibly repair the unit) requires taking the outside shell off and cleaning the contacts of the safety switch with either a small, fine file (like the old ignition files) or maybe fine emery cloth.

It heats for a minute or two and then stops heating.

The heater overload switch is sensing an over heating problem and is turning the unit OFF. It may be as simple as a clogged heating element. Over time they do become clogged with dust, lint, pet hair, etc. This is because the air intake for the heating element is a floor level. So, whatever is floating in the household air gets sucked into the heating element when the fan is ON. Using a vacuum with a hose and brush attachment works well in cleaning the heater element. Be sure the unit is OFF & unplugged, before attempting this. You may be able to access the heating element thru the lower louvered door. Or consult your Owner's Manual regarding the cleaning of the unit.

I hope this helped you and thanks for choosing FixYa.

On my electralog heater, after about 5 minutes running the heat stops,fan is still running. Adjusting thermostat makes no change

From what you have described. it sound like the heating element is overheat and the automatic over heating sensor is shut it down. One of the primary reason these heaters overheat is that the become clogged with dust, lint & pet hair. Cleaning the heating element. may solve your problem. A vacuum cleaner (especially a Shop Vac) that has a hose, a brush attachment and a crevice tool, works well well in cleaning the heating element. Be sure the unit is OFF and unplugged, before attempting any cleaning.

Hope this helps you solve the problem.

I have a charmglo electric fireplace blower works but there is no heat is it the thermal cutoff and if it is what do I replace it with and also can it be put in backwards

More than likely it's the Thermal overload circuit or the heating element has given up the ghost.

As I just told one other questioner. These types of electric fireplace heaters were not designed to run for long periods of time. Their heat output is not much more than a blow drier. However, this is not just a problem with CharmGlo, it's with all the manufacturers.

Here's the problem ... The heaters work by taking in cool air, heating it and sending it back out via the blower. Over time, the heating element and/or blower become clogged with dust, lint and/or pet hair. This makes the heating element work harder and it over heats. Either burning out the heating element or the thermal overload switch or both.

You can try cleaning the heating element with a vacuum that has a hose and a brush attachment. While you're at it clean the blower fins and motor. Consult your Owners Manual to see how to access these parts, as they are under firebox, behind the metal grill on the bottom of the firebox, so to speak.

My Dimplex DFB 4047 won't get very hot

This is an on going problem with electric fireplace/stove type heaters of all types. Not just Dimplex.
They are not designed to run for long periods of time and the heat output is not much more than a blower dryer. In any event, they take in cool air, heat it and send it back out. Over time, the heating element becomes clogged with dust, lint and/or pet air. So, they have to work harder to produce a sufficient amount of heat. Cleaning the heating element with a vacuum that has a hose and brush attachment may help. The heating element and blower are under the stove. See your Owners Manual on how to access it. Be sure to unplug the stove before trying to service/clean it.

It makes a lot of noise and its dirty inside. I just wanted to know the best way to clean it

use a compressor and a blow gun attachment blow the air thru the fan opening then back thru the heating elements do this several times back and fort until you get no more dust from the heating elements. I have done this on my own heater and it works just fine. Try this and you will find yourself cleaning the heaters each year this way with out taking them apart.

The heating element inside of my York Air Handler only lights up one side of the element and I can not figure out why only half is heating up.

Check the wiring and make sure there are wires connected to each side. If not then attach any loose wire found not connected.If all the wiring is ok, then check your element for a broken spot. Repair if found. If none of these thi8ngs are found then your element is burnt out on one side and needs to be replaced.

Lasko heater shut down

The 5840 has a problem with dust getting on the heater element and turning itself off after 2 minutes running. HERE IS THE FIX. Unplug the unit from the AC outlet, Then using a can of dusting air ( the kind you use to clean a computer key board) aim the compressed air INTO the middle louver of the upper adjustable heater vent and blow out the dust that has gotten on the heater element. ( You are actually blowing into the unit, clearing off the lint/dust that has gotten on the backside of the heater element that you can not see without openning the entire case).You can see the front of the heater element inside the louvers, It's the shinny metal part that looks like a small radiator.It sits behind the middle louver. After blowing out the dust, shake the entire unit to allow the dust to settle to the bottom of the case. Using a vacum cleaner try to vacum out any dust from the LOWER FRONT intake. Once the dust has been blown OFF the heater element, the unit will work just as new and not shut itself down!

Portable Heater keeps turning off

I just fixed my Stanley Lasko 675900 FOR GOOD and would like to tell the world how to fix it!

1. Remove the front plastic grill. The bolts are torx heads with a center pin. You may be able to find a torx head driver with the center pin but I improvised. I Used a dremel tool with a small rounded diamond bit to grind the center pins out of each screw so I can use a standard torx head driver on the screws.
2. Remove the heating element. These should be Phillips screws.
3. Blow out the dust from the back side of the heating element. (be careful with the fragile fins)
4. put it all back together and it should work just fine.
5. (optional at your own risk!) I believe the small gadget attached to the top of the heating element with the white wire is the limiter. You can use pliers to slide the unit out of the element and either move the unit further toward the center area, or cut the device out completely with wire cutters and then splice it back together. If you do this REMEMBER TO CLEAN THE BACK OF TH HEATING ELEMENT EVERY MONTH TO PREVENT A DUST FIRE!

I hope this work for you and good luck!
