Good chance it is overheating. Make sure you clean the pre-filter (the metal tube inside the dirt collector) and pull out any other obstructions in there. More likely, though, you must clean the black square filter on the outside of the dust collector. This may help: https://www.youtube.com/watch?v=K3MumYn9C70

No you replace a burnt out fuse with the same value fuse if you would like to continue to be able to use it
if you use a 15Amp fuse you will be allowing 5 times the current to flow through the current sensitive electronics and that will not sell for the board's

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.

Any decent electrical shop should have those fuses. They tend to come in 20mm and 30mm lengths. You will need to know which. Also there are fast blow and slow blow fuses. If you have the originals and you can see the remains of a coil then you want slow blow. Otherwise just replace them with fast ones. The 1.2 amp fuse can be replaced with a 250 volt fuse.
So you want a 250ma 250v fuse.
and a 1.2A 250v fuse.

AUTO SAFETY SHUT OFF

The heater has a built in safety device which

will switch off the heater automatically in case

of accidental overheating. It can only resume

operation when the user has reset the unit. For the

BPH1520 (OH)will display in an overheat situation.

To reset the heater:

1. Unplug the heater and wait for 30 minutes

for the heater to cool down.

2. After the 30 minutes, plug the heater in

again and operate normally.

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....

The cheapest place I have found is amazon. here:
QUALITY USA brand fuses Set of 5 pieces T3 15AL250V T3 15A 250V T3 15L250V... (you can search from another sellers, but this one had most positive reviews). I hope this was helpful. cheers
