Hello, to reset remove the panel over the gas valve and burner area, look for 2 or 3 black plastic devices about the size of a 50 cent piece with a red button on them, push the button, if one of them clicks when you push it, you have reset the furnace.

Look for any other similar item inside the burner area and reset it it as well.

let me know what you can discover, We can go from there

there are no black devices with red buttons in the gas valve area or the fan area. there is a 3amp fuse next the door switch that leads to electronic board but this appears not to be tripped.
