Question about Bionaire BCH-4138 Ceramic Compact Heater

1 Answer

Heater shuts off as soon as the room is warm

I usually set the temp at 71 and set it in the auto - low mode. But as soon as the room temp is 71 say from 67 or 68, the heater turns itself off.

It was working perfectly last winter, but now it's not reliable 'coz as soon as i am asleep - it's stops working and i wake in the middle of the night 'coz it's too cold.

    Thanks a lot Will.


    I did try it last night by setting it in the high mode and it worked!! It did not shut itself off.



    Now, how would i fix the mode problem? Should i fret about it or just be happy that it works in the high - auto mode?



    Once again, thank you very much.

I take it once the temp is set to 71, and the ambient temp reaches 68 or so, it shuts off, never to come on again?

If that is true the thermostat in the unit is damaged, worn out or in need or replacement, but try a couple tricks.

First, if there are access panels to clean, clean it per the manual, it could be that a dirty filter or air inlet is confusing the thermostat.

Next, unplug the unit for at least 5 minutes, try it again.

Next set the unit on it's highest temp and blower setting, let it rip for 20 minutes, shut it down, unplug and remain unplugged for 5 minutes.

Next set the unit at 71 HIGH MODE.

see if we have a mode switch problem or thermostat if it works on high mode, it is not the thermostat, but I imagine it is, but I am curious as to if it once goes off, it never again comes back on?

    You are welcome, I fret over everything I cannot see, just for safety issues.

    I volunteer on this site, I volunteer on allexperts.com, my shop is EMR Repair Inc in Kansas City Missouri.

    I say that because sometimes things are critical and people can't find anyone, or take advantage of people in a spot.

    My guess is the mode thing, being on low, tells me the unit is dirty, and the low air flow on the auto low, is causing either a perfectly working overload device, or a weakened overload device.

    Space heaters are the culprit in so many fires, and you are sleeping when this one fails,

    So how do I say without my liability on the line, and your health and welfare on the line, that all is fine?

    I doubt there is huge problem, I doubt you need to fret, but you are more important than a space heater.

    I assume that funds are an issue, if I am incorrect, look into a new infared bulb type heater, they are as cheap to run on electric power as any element electric space heater, safer, don't dry out the air, cheap to run, and look nice.

    Fret no, concerned, yes, any space heater should operate in any mode, without fail, especially if you are sleeping with it on.

    Speaking of safety, how are your smoke detectors, in place, new batteries, tested RECENTLY?

    That would make me feel better just knowing that.

    If funds are an issue, and you promise there is a tested working smoke detector, I will say plan on doing something about this heater as soon as you can afford to, a smoke detector if you have to pay for it, is maybe $10.00. Some Fire Departments give them away.

    Get the smoke detector, get it working or promise you have one in good shape,

    Then tell me what size or what the nameplate data is on this heater, and we will go from there.

    I don't know if you are talking a 400 watt or a 1000 watt.

    Let me know what heater we are dealing with and I will do my best to help you more, I will look it up and if I can tell you what goes on with that type heater.

    Get the detector working and no fret, no detector FRET.

    Will

I HAVE A MODEL HOE-HT-L2 THE INSRTUCTIONS ARE NOT CLEAR AS TO SET THE TEMP CONTROLS


Greeting Cyril Hrachovy,

"Say" 22 is an example... You should input whatever temperature where you are comfortable ...

Our master bed room has it's own controls... but usually the vents have been blocked shut... or have magnetic diverters (plastic shields) on the vents... where the thermostat is all warm & happy across the room while I'm freezing against the glass...

A happy medium has to be struck
- between the IVORY-TOWER instruction writer... and
the sun soaked rain drenched REAL WORLD in which
we live (I'm just saying).

Programmable THERMOSTATS are get (fun)... but in reality
the automatic features are soon abandoned... (harmony)
and the REMOTE favors the fickle.

Have installed a new Honeywell thermostat. The fan does not turn off even when the room has reached the desired temperature. I originally replaced th ethermostat because the old one the fan ran forever and...


Most T-Stats have a On / Auto on a forced air system. On means the fan will run all the time even if it is not calling for heat. Auto only runs when calling for heat. Does the fan turn off in the auto mode at all? To test it...BE SURE THE FAN IS IN THE AUTO MODE ON THE T-STAT... Turn the thermostat all the way down and keep it there for appox 15 mins. If it is wired properly and the fan limit is set properly the fan should turn off. If it doesn't it is not the thermostat were the problem lies.

Most forced air units have a fan / high limit switch. There is a setting on the switch for the fan to turn on and a setting for the fan to turn off or it has a setting and a differental switch for it to turn off/on. Example - the fan comes on when the temp in the heat exchanger reaches 110 degrees F and will shut down at 95 degrees F after the thermostat is satified...this would hav a differental of 15 degrees F. It may be set to low and the fan continues to run long after all of the heat has been removed from the heat exchanger. This in turn will cause cool air to be coming out of the registers.

HEATER NOT WORKING PROPERLY (SOME HEAT BUT NOT HOT) COMPRESSOR NOT RUNNING WHEN IN HEAT MODE. A/C WORKS FINE.


No adequate heat due to wrong setting temp or your RV (Reversible valve) not working properly.
Set temp +5 than your room temp and mode in " Heat". And check click sound in reversible valve and also warm in sunction line.

If it's with heating element check power goes heater coil. If not check wiring.

Have model MD300TGA with blower.Blower is set on auto but doesnt kick on.When should blower start up after room has reached desired temp. and heater has shut off?


There should be a limit switch and once the heater reaches the set temperature the blower gets signal from the limit and that turns on the blower. If you are not getting the blower until after the room is up to temp then it is coming on it may be the low limit is bad and it is cooling itself down on the high limit. If you are unsure of this please consult a heating service person, this is a serious problem that a trained service person should deal with. This can lead to a house fire!

Press the *power button* once to start the heater on high power, continuous run. If left at this setting, the unit will run continuously on high power (1500 watts, 12.5 amps) and will not shut off until the unit is manually turned off.
Press the *power button* again, to change to low power, continuous run, (900 watts, 7.5 amps) and will not shut off until the unit is manually turned off.

Set temperature:

Press the temp/timer button until the temperature icon blinks. Use the up and down arrows to set the desired temperature.
The temperature icon will stop blinking and the current room temperature will reappear after the desired temperature is set.

The heater will turn off and on to achieve the desired temperature.

Set timer: (auto off)

Press the timer/timer button until the timer icon blinks. The hour display will appear. The auto off icon will also appear.
Use the up and down arrow buttons to set the heater operation time between 1 and 10 hours. This function will activate once the timer icon stops blinking. The heater will automatically turn off whn the times runs out.

Set timer: (auto on)

Press the temp/timer button until the timer icon blinks. The hour display will appear. The auto on icon will also appear.
Use the up and down arrow buttons to set the heater start time between 1 and 10 hours. This function will activate once the timer icon stops blinking.

Hope this helps!
