sounds like you have bad flame sensor or the sensor is in a bad postition. To get eliminate the lockout turn the power off to the unit and back on again. Look at the circuit board light and see what the troubleshooting code is.

SOURCE: Gas valve lockout

It means that the furnace isn't igniting and for safety the control board is preventing the gas valve from opening. Turn off the power to the furnace for a few seconds then observe what the furnace does in heat mode. Some furnaces will run the blower for a minute after you power it back up. After that see if the furnace tries to come on. If you are still getting the code then one of you high temp limit or roll out switches has tripped. Now is the time for a service tech. Make sure that you check you filter and air flow too. Low air flow means the furnace may be over heating.
The other thing is the hot surface igniter. Look closely at it with the power off. Do you see a white spot on the element or a crack. If so the HSI is bad. It's an easy replacement but DO NOT touch the carbon element with your fingers and be very careful handling it as it is EXTREMELY fragile.

SOURCE: Kenmore furnace mdl BGU100168 status

Can you please verify the furnace mode, nothing comes out with the BGU100168 model #. Is it an oil or gas furnace? Was it bought at Sears?
In the mean time you can try cleaning the filter, with a piece of emery or sand paper sand clean the flame sensor (thermocouple) in front of the pilot light (if applicable). Reset the unit by disconnecting the power for 5 min. and tuning it back on.
Keep me posted!!

Heil gas furnace soft lockout how to fix it

I have a Ruud Achiever 90 Plus furnace that will not ignite and is showing a 'soft lockout' code on the LED panel. I've tried restting the furnace as per the manual and still no results. Am I missing...


Hello. a soft lockout typically happens when

1) the flame sensor is not detecting the flame
2) pressure switch fails to close

Since your burners are not igniting I would check the pressure switch, make sure there is no obstruction in the flue pipe, the hose going from inducer to pressure switch is not kinked, loose, obstructed, or have water in it. If that all checks out good then your pressure switch is bad and must be replaced. If you need any further assisatnce let me know

Plenum seems to be heating up but blower fan cuts out before it can blow heat through the house


Probably a bad fan/limit. The way it works is the heat comes on first then as the air gets warmer the bi-metal twist around on the fan limit and at around 110f the fan kicks in. If the fan don't kick on then the limit kills the heat so the furnace don't get too hot.
Newer furnaces use a computer board to drive the fan with a timing sequence.

Of course it could be something very simple such as a contaminated flame sensor. If your furnace if one of them fancy new fangled machines which use a draft inducer fan the control may not be sensing ignition and auto cycling on and off. if that is the case get a dry brillo pad and remove the sensor. Give it a good clean and re install it then retry:

I have an older sterling gas furnace hung from the garage ceiling that cuts out intermittently . It does not trip the breaker but often if I reset the breaker at the fuse panel box it will start up.


Hi,
The heater is going into "lockout"... it should be flashing a code on the ignition control that will tell you why it went into the lockout condition...

My guess would be that the high limit switch is bad or going bad and it is cutting out when it shouldn't be... or the flame sensor is loosing contact and cutting the burner off...

You could try to clean off the flame rod with a soft cloth...

This is a Dayton gas furnace model GF9S120D20UP11H and i am getting a flash code of ignition lockout due to recycles. how do i fix it? i have taken all the filters out and washed them and also checked...


Usually a lockout code means it tryed so many times and then it locks out or stops. First, when a furnace is locked out you have to kill the power to the furnace to reset the lockout. I don't know this furnace but there are manual resets around the burner called flame rollout switches that have buttons in the middle that have to be pushed back in. Also the power vent has to come on when the furnace gets the signal from the thermostat. This is proven by a flow switch with a rubber hose on it. The next step is a 30 sec. purge, then the igniter glows or sparks and then the main burner comes on.
The other switches are hi limit on the front wall of the heat exchanger. That might get you started. If you have anymore questions rspiak1@cogeco.ca

• Loss of flame after establishment.
Cause may be
interrupted gas supply, lazy

pressure or restriction in flue
and/or combustion air
piping), front cover pressure
switch opening, or improper
induced draft blower
performance.
• Locate and correct gas
interruption.
• Check front cover

operation (hose, wiring,
contact operation).
Correct if necessary.
• Replace or realign
igniter.
• Check flame sense
