20 Most Recent Bionaire BCH-4138 Ceramic Compact Heater Questions & Answers

Difficult to guess what the problem might be due to the amount of electronics the unit has that could cause inconsistent or illogical functioning.

I noted one product review that said "if the room is too large the auto shutdown will engage".

I suggest you revisit the instruction manual and specifications before deciding whether to call a service engineer....

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?

The capacitor winding in the motor presets rotation direction. Without the capacitor, the motor will not know which direction to rotate. With a bad capacitor,or with no capacitor connected to a capacitor motor, turning the motor shaft by hand will cause the motor to rotate at operating speed in the direction manualy spun, so, the motor can rotate either way once started by hand. This proves a bad capacitor. If the motor just sits dead while energyzed, then the motor is open electricaly, usualy a thermofuse embeded into a winding goes out.

I have the same problem. This is what I found when I look inside.
I think this could be a quality issue with significant safety risks.
I hope this isn't typical of their products.
