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.

Heater won't stay on, I heard there was a recall on this item.

Hi and welcome to FixYa, I am Kelly.
I am only answering part of your question (Recall) so do not rate the post so other experts can help you with your heater won't stay on problem.
Your heater model is not one of the 4 models that were recalled.

The recall involves Holmes® models HFH6498-U, HFH6500-U and HFH6500TG-U and Bionaire® model BFH3530-U. The recalled heaters also have date codes beginning with 2604 through 3804 for all units, except for Holmes® model 6500TG-U, which has date codes ranging from 2604 through 4704. The model and date code can be found on the silver label on the back of the unit. The heater fans are 26 inches tall; come in all gray, two-tone gray, or black and gray; and have either the word Holmes® or Bionaire® printed on the front of the base.

For some reason the heater does not generate heat. the fan works but no heat. Any Ideas?

I've got an easy way for you to check, and then we can help you from there.
First pop open both lids to your furnace (this may require a screwdriver). Turn up your thermostat, push the safety interlock button in if it has one (it's a button that turns off the power when the doors are removed), and watch.

On most modern furnaces (past 20-25 years) you'll hear/see:
1. Inducer fan
2. orange glow (ignitor)
3. Gas valve opening and ignition (flames)
4. Main Fan.

that's normal heater operation.
The most common issue here is a burned out ignitor, in which case you wouldn't see the orange glow but the sequence would attempt to continue anyway (the gas valve will open and hiss gas, but it won't lite, then it'll give up and try again a few minutes later).

On older furnaces there's a pilot light to start with, the click of the gas valve and boom... ignition.

On new furnaces it's
Inducer fan
gas valve opening
spark - ignition
Main fan.

and there are some oddballs in between, particularly the Lennox Pulse. If that's your furnace just back away slowly and call a professional... some guys won't even touch those, so be sure to mention what it is... if you call a pro.

So go ahead and watch it run, then tell me/us what you see.

I have the bionaire oil heater boh2513g. I placed a towel over it to dry and I think it's went into overheating safety mode because the three lights are flashing but the appliance wont come on. Is there...

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.

Can't get heater to restart using remote control & 2 small green lights on heater flashing on & off

Have you tried replacing the batteries in the remote control? That may be part of the problem.
If you have already changed them, unplug the heater for 30 minutes to allow it to reset itself.

Hope that solves your problem.
