The ignitor starts and the gas goes on but the blower does not always come on with heat, and it is not because the house is warm enough that the thermostat is higher than the tempature set.
Sometimes the ignitor starts and then goes off and the blower starts with cold air.
What could cause this if the ignitor was replace and the filter was just replaced?
It's weird that the blower would start without the ignitor and send out cold air. My heater does the same thing, except the blower never stops once it's started even when the ignitor goes out. I'm not sure if we have the same problem, but I think it would be best for both of us to have a residential heating service take a look at the problem. http://www.tristateenterprise.com/heatin...It's weird that the blower would start without the ignitor and send out cold air.

yes, make sure you order the correct part, youll need the model number and serial number. the ignitor has 2 wires wrapped with white fibers, usually 2 screws to remove it, and theres only one way to plug it back in. NOTE: Ignition failure does not always mean the ignitor needs replaced. make sure your ignitor doesnt turn on and glow when you start the heater. if it does, youll want to clean out the gas orifices.
There is an ignitor and a flame sensor. If the ignitor does not ignite the gas after a time, it goes out. If the flame sensor does not detect ignition the gas valve closes. When you start it you should see the ignitor come on like a light bulb and glow, then the gas valve opens and you get ignition. Then the flame detector turns on when the ignitor goes out. Flame detectors are like a chrome wire that has one connection to it and it sits part of the way in a burner. They get dirty and corroded. When that happens it shuts down. You can clean the flame detector with steel wool of scotch brite pads. Dont get too carried away doing that though.
The basic gas assembly is like that of many American gas dryers of various brands. The power going to the gas assembly comes from the control which is mounted next to the fuse on the blower housing. The control of course gets its power from upstairs via the timer. If the air temp is below that which is required the bimetal inside the control will allow power to go through it and the thermal fuse over to the gas assembly which consists of a flame sensor, an ignitor, and a coupple of control solenoids. So if the control has power and continuity and the fuse is good and power gets to the gas assembly then the ignitor should start to glow. When it gets up to temp it should bend the bimetal in the sensor and shut off power to the ignitor. The ignitor is now a thermocouple, as long as it is glowing it will allow the solenoids to operate. If for some reaon there was no ignition of gas the solenoids will not work when the ignitor cools down. The ignitor stays hot from the flames coming off the burner. So we have ignition now and a blast of heat going into the drum. The rush of warm air is being monitored by the control mounted on the blower housing next to the fuse. When the temp gets up to snuff, the power is shut down to the gas assembly and the flame shuts down. The drum continues to turn and when the temp drops another balst of hot air is called for. So what goes wrong? If it heats some but quits them solenoids are bad. If it clicks but no ignitor then wither the ignitor or sensor is bad. My home movie:
Hi,
If you are having problems with your gas dryer not heatingthe most common problem is that the ignitor goes bad. Even though it glowssometimes it is still not working properly.
if you dryer is gas check out this gas no heat tip....
If you have an electric dryer, you can have many differentthings that can go wrong causing the dryer not to heat.
check outthis electric no heat tip...
Problem: Your furnace will not
ignite the gas to produce heat for your home. When a furnace has a bad ignitor
what I see most of the time is the following sequence of operation:
1. Thermostat calls for heat.
2. Draft inducer motor starts.
3. Pressure switch attached by a small plastic or
rubber tube senses the negative pressure produced by
the draft inducer and closes.
4. Draft inducer runs for 30 seconds to a minute
before you hear a gas hissing sound. The ignitor did
not glow, the flame sensor (a small metal probe about
1/8" in diameter, with a white porcelain base) does not sense the flame, so after 8 to 10 seconds the hissing sounds stops
with no ignition of gas to heat your home. Your
furnace shuts down and goes into a lock out condition
until you turn your power switch back off and on
again. Then the sequence starts all over again with no ignition of the
gas.
Solution: You
probably need to purchase and install a new ignitor. I would suggest that you
inspect your ignitor closely for cracks. Make sure
you do not touch the ignitor with your bare hands. If
you do not visually see a crack, then you could have a furnace control board
problem or a limit, rollout switch problem. The furnace's
control board might not be supplying the voltage to the ignitor. If
your furnace lights and the gas stays on for 8 to 10 seconds, then shuts right
back off, then you need to clean your flame sensor with light sand paper or
steel wool. You might need a new flame sensor, but most of the time they can be
cleaned an will work well after cleaning.

Hi, Gas valves works off of amps pulled by the ignitor...ohms doesn't matter..
If you are having problems with your gas dryer not heating
the most common problem is that the ignitor goes bad. Even though it glows
sometimes it is still not working properly.
if you dryer is gas check out this gas no heat tip....
If you have an electric dryer, you can have many different
things that can go wrong causing the dryer not to heat.
If you do not see a bright light before the gas releases, your ignitor is probably out. If you disconnect, you should measure ohms from the two ignitor leads. If you do not measure any, it is open and will not work. You will usually see a mark of white on the ignitor. Another possibility is the circuit board may not be sending the required voltage to ignite the ignitor so you'll want to check that too.
If the flame looks good prior to the room air blower starting but becomes unstable when the blower starts, you have a crack or hole in the heat exchanger. I strongly suggest your technician do a test on it to see.
