Frigidaire furnace model # FG6RA 096C 16B

When I replace the metal cover on the unit the the gas flame comes on turns blue and right before the blower kicks on the flame goes out and the blower just blows cold air. When the cover is off or even just not completely covering the opening the unit has no problem. What do I need to check?

How do you adjust the pilot light flow on an old magic chef heating unit/ceiling mounted furnace?


How long is the pilot flame? It could be you can move the thermocouple into the flame by making adjustments of the metal holder. If the flame is small, there is an adjustment for the piolet flow in the control module where you turn gas on and off and light the pilot. It should be labeled and usually has a cover that must be unscrewed to reveal the adjusting screw. Need a bright flash light to see what you're doing.

Dayton gas furnace model 3e385 works and lights but as soon as fan comes on the unit shuts off and lights again wondering what was wrong


Check heat exchanger for cracks or holes which will cause the fan to blow out the flames. The flame sensor on the pilot or burners has to be in constant contact with flame to operate normally. If the flame is put out by a cracked exchanger the exchanger or furnace needs to be replaced.

Nordyne furnace. The furnace comes on, flame comes on, blower comes on and then works for about 3 second and shuts off. Then starts the cycle all over again.


Hello. The first thing you can do is check the flame sensor, this is a small metal rod on the opposite side of the ignitor, Turn off power to the unit remove flame sensor and clean it with some steel wool. Also check the flame sensor to make sure there are no cracks in the base of it, if so then replace the flame sensor. If you have checked the flame sensor and the problem still continues you might have a problem with the unit not being grounded properly, you should have a ground wire coming from the main electrical panel to the furnace. If the ground wire is there and problem continues the control board should be replaced. I hope this helps.

My heat won't blow through the vents. The furnace ignites itself but it cuts off after a minute. I've sanded the flame sensor but it still won't work. What can I do now? I just want heat in this blizzard!


If the ignitor glows and the burners lite and then shut off, the flame sensor was the best place you could
start at.

If this is a reg gas furnace or a High EFF. furnace make sure your gas meter is not covered up with
snow.

Turn your thermostat all the way up, if the furnace
does this 3 times in a row-then it should go into
a lock-out mode. Has it done that?

On reg. gas furnace make sure your chimney is
not obstructed where it connects to the furnace.
If it is a High EFF furnace make sure the pvc exhaust
vent is actually venting. It should also have a pvc intake air vent make sure that is not clogged.

If it is a high eff furnace, turn unit off and remove
the door that covers the ignitor and burners. This is
usually a interior door with a sight glass in it. Turn
furnace on, if it lights and stays operating, then you have a problem with the intake vent

Furnace won't stay running


1
1 FLASH
Furnace fails to operate.
• Integrated control module
diagnostic LED is
flashing ONE (1) flash.
• Furnace lockout due
to an excessive
number of ignition
“retries” (3 total)1.
• Failure to establish flame.
Cause may be no gas to
burners, front cover
pressure switch stuck open,
bad igniter or igniter
alignment, improper orifices,
or coated/oxidized or
improperly connected flame
sensor.
• Loss of flame after establishment.
Cause may be
interrupted gas supply, lazy
burner flames (improper gas
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
pressure switch
operation (hose, wiring,
contact operation).
Correct if necessary.
• Replace or realign
igniter.
• Check flame sense
signal. Sand sensor if
coated and/or oxidized.
• Check flue piping for
blockage, proper
length, elbows, and
termination.
• Verify proper induced
draft blower performance.

Williams wall furnace, top vent.


I've replaced a Williams wall gas heater non-electric. The thermostat is connected right and mounted on the wall. But, there's a thick black copper wire on the side of the furnace tagged thermostat. I don't know what to do with it? Where do you connect this wire? When it touches the top screw of the three screws running vertically(where the other wires are connected). The burner lights up and stays on, even if you play with the wall thermostat. Touching the other two screws doesn't do anything. Now, the manual talks about connecting it to the venting wires? Extra wires coming from the top or maybe somewhere else in the wall? I've left it connected to the first screw, ran the heater. But, it never turns off? Any suggestions? Thanks

Flame Adjustment


Make sure the unit is operating on the correct gas, Natural or Propane (LP). The sound you are experiencing is either not enough gas and the flame is burning inside the burner port(s) or too much gas and the flame is much larger than it has to be. At any rate, get a technician to check the gas pressure entering into the home. NOW!
