Bionaire BH3950 Does not heat

My heater just wont heat, the power light is on but the appliance will not produce any heat even if it is turned on to high. On the opposite side it has instructions in case it shuts off. It says to turn mode to OFF and thermostat to high, unplug and then wait 30 minutes. After that you plug it back in and turn mode to on and tara! it should work... Well I did that exactly more than 10 times already and it doesn't do anything for this heater to work back again. I don't know whatesle to do. Please help!!!

Re: 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.

Re: Bionaire BH3950 Does not heat

The thermostat seems to be faulty or the heating element is burnt out.

My Bionaire BCH9221um wont turn on.

You might want to open it up and check the thermal fuse. This is usually a small cylindrical device with a cone at one end and wire leads coming out of both ends. It opens permanently when it gets over a certain temperature, and sometimes will open prematurely. Check it for continuity with an Ohmmeter. If it is open, then it is the problem. You can usually read the temperature, or a part number on the side. Look it up on the web, or go to your local electronics parts store. You can get one for a buck or two. Replace it by crimping it on to the wires, do not attempt to solder it, as the heat will likely destroy it.

Good Luck.

My chauffe air heater will not give off any heat

see this causes and fix it. God bless you
If an appliance that should produce heat does not, inspect the element for breaks or obvious damage. If you don't see any damage, test the element for continuity (see below).
  1. Turn off power to the appliance or device. If the unit is plugged in, unplug it from the electrical receptacle (outlet); if the device is wired into the circuit (such as an oven), turn off the circuit at the electrical service panel.
  2. Disassemble the appliance or device to access the heating element, following the guides in this book for your appliance. Some heating elements, such as plug-in units in electric ovens, are relatively easy to remove (see the Electric Oven Fix-It Guide).
  3. Set the multimeter to RX1 (resistance times 1).
  4. Touch the multimeter probes to each end of the element.
  5. High resistance (kilo-ohms or thousands of ohms) indicates the heating element is okay. A reading of infinite resistance indicates a broken element.
  6. If a heating element is faulty, replace it with one of the exact size, shape, power rating, and resistance.
  7. Reassemble the appliance or device and turn it on or plug it in to test it.

Heater bionaire bch9224-cn no heat

The Bionaire BCH9224-CN is a ceramic space heater, one of apparently 4 related units. The 9224 is the tallest in the family and I also have the shorter BCH9212-CN. They are electric so I have no idea what all this talk about 'gas', 'pilot light' and 'flame' is. My 9224 failed in a way that seems quite common with Bionaire space heaters in general, namely, first the smell of burning electrical insulation, then a snap or pop accompanied by a flash of light out the lower side, and then no more heat. It is possible that the original questioner had this happen but wasn't around to witness it. Now it is possible that the failure is in the electrical control board but in my case (and in fact I'm betting for many or most of the Bionaire failures) it was a wire running to the ceramic heating block (element) that fried at the connection to the ceramic element. I would say it is very unlikely the failures of the Bionaires are in the ceramic heater blocks themselves, and in fact the 9224 and the 9212 (and I assume many or most of the other Bionaires) actually have two ceramic blocks/elements fastened together, one being used for the 750 watt heating and both for the 1500 watt heating. The central wire running to the blocks must support enough current (about 12.5 amps) for both of the blocks, whereas the wires to the individual blocks need half that (about 6.25 amps). In my 9224 unit the weak spot was clearly where the central, common wire was connected to the spade-like connector that was crimped onto the central, common tab of the ceramic block pair. At first I thought I'd just toss the thing but then I opened it up, did the autopsy and repaired it by replacing the 3 wires from the circuit board to the ceramic blocks with 14 gauge wire, and made the connection of the wires to the three soft metal (tin or tin alloy?) tabs of the ceramic blocks by carefully drilling holes in the tabs and bolting eye, crimp-type wire connectors to the tabs using small screws. Oddly enough I opened up the smaller unit (the BCH9212-CN) and it has the same ceramic element pair but no indication of burnt wires.

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.

Turn the Master switch to OFF and plug the heater and leave unplugged for 30 minutes, That should give it time to reset itself. If it doesn't work after that, it's probably fried.

1 Answer my bionaire bch9221 120 volt heater does not produce heat anymore.....i'm thinking that maybe an element within the unit is burned out.

Mine was doing the same thing. Took it apart and found that the white wire which hooked up from the circuit board to the heating element had burnt which broke the connection...hence no heat....replaced burnt wire and resoldered to heating element...put it back together and voila I have heat once more....still doesn't solve why the wire fried though....

Heater won't turn on, the lights keep flashing.

HI There is a product recall for this particular model of heater, you can search the internet for details on how to get the item collected by Bionair and get a full refund, these are a fire risk.
