By and large, electronic devices need the smoke to stay in for them to work. Once the smoke comes out, they generally don't work anymore.

Joking aside, the only parts that can generate enough heat to produce smoke will be the power supply transformer and capacitors. If you're lucky, the damage will be limited to the power supply, but there's a good chance that it went unregulated while it was failing and so dumped 120V into the main circuit board and cooked other components there.

If you are up for soldering, then open the unit up and post details of what components have visible damage, as well as detailed info about the circuit board revisions.
If you're not, then it's probably time to shop for a new receiver.

How do I clean the dust from an Amish fireplace

This shut down is a safety feature on the unit so it doesn't over heat.
You need to remove a cover that's in the back on the bottom and
take compressed air to blow out the dust. Concentrate on the
blower especially. Best done out doors.
This is also a good opportunity to see if the blower still turns
freely. If not it'll need lubed or replaced.

There are four possible answers to this problem, if the heater starts normally, runs for a few seconds or minutes and the shuts down but was still running normally at the time of shut down, this could be caused by the photocell, also known as the flame out control. This safety device may be failing, shutting down even though the heater is working normally, check the operation of the photocell. The second cause may be partial fuel filter blockage, the heater is effectively starving itself of fuel, so the flame blows out, hence the puff of smoke, and then shuts down on the safety cut out. Third cause, if this model has a compressor at the rear of the motor, the problem could be low pump pressure, caused by wear or contamination of the carbon blades, this would cause the wrong amount of fuel to be syphoned up, with weak fuel mix the heater may blow itself out and shut down. The fourth cause, perhaps indicated by the puff of white smoke, is contamination of the fuel with water, water will cause the white smoke and also is indecated by white residues or a power like substance on the end plate of the heater which glows red hot when burning.

Program shuts down during exercise. Resets to default program. As if rebooted. have all new parts,(alternator, key board, gray cable, resistor, power input )


I am having the same issue with my 4XXX StairMaster unit.

I am suspecting that the voltage regulator on the lower board is at fault and that a lower board replacement is in order. I have checked everything else (motor, resistor, power supply).

Try this:

My machine REBOOTS if I choose:

- Rolling Hills
- 200 lbs
- Difficulty 20
- 20 minutes

My machine OPERATES NORMALLY when I choose:

- Rolling Hills
- 200 lbs
- Difficulty 1
- 20 minutes

Apparently, the problem only manifests itself at HIGH RPM, which is probably related to a LOWER BOARD / VOLTAGE REGULATOR issue.

My heater is brand new and worked for 3 days. i have no heat, i also have 4 flashes blink code. indicates high limit/ rollout switch. i have rechecked the thermastat, gas line and the vent pipe, the fan...

There is something else that is causing the Overload/Roll Over Switch to trip. You can try unplugging the unit from it's electrical source and wait 30 minutes before plugging it back in. That may allow it to reset itself. Unfortunately the Overload/Roll Over Switch is preset at the factory and is not adjustable.

If the unit resets itself and starts working again, but then shuts down, check your Owners Manual for other causes. If you've misplaced your Owners Manual, here's a link to it, that you can download and print.

Hope this helps to get you headed in the right direction. If all else fails, call the Technical Service Dept at the number listed in the Owners Manual.

Starts runs for a minute two the shuts down and blowes smoke

jerome kr406,

This is a classic problem with the reddy heaters. They have a filter which over time plugs up. This causes the air/fuel mixture ratio to change because the pump pressure is determined by the air bleed. As the filter plugs the air pressure drops and the fuel also drops meaning the burner is running lean. This eventually causes the unit to shut down and as you said smoke comes out. It is a fairly easy fix and I have a tip which will walk you through it at . My tip will link you to the place to get the parts you need as well as how to perform the additional maintenance that these heaters require.

Thanks for using FixYa and for the excellent rating. Great ratings help to keep experts helping everyone solve their problems. Thank you.
