Turn the power off to the furnace, turn the thermostat to the highest heat setting then turn the power on. The fan may start for a brief period, then the combustion blower will start, after approx 90 seconds, the ignitor will light and heat up. You should be able to see a glowing in the burner lens. If you do not see a red glowing, similiar to a car lighter, that would indicate the ignitor may have failed. If after 3 attempts, the systems fails to light, there is a light on the circuit board that will flash, the number of flashes will indicate the reason for the fault.

Samsung gas dryer dv350agp/xxa have lights come on but is not working

It could be that you have a broken belt. Can you heat a motor running? Try placing your ear to it when you turn it on, if you can hear the motor running then remove the back panel and see if the belt is in tacit.
Best of Luck

Does the vent motor come on when you turn on a powervent hot water heater

`1) Copy following link to troubleshoot by type of gas control valve, blower motor links, pressure switch testing, and other professional resources:

2) Power-vent blower motor can go bad.
Plug motor directly into outlet, or turn on-off switch on, and see if motor works.
Check outlet for correct polarity, and for at least 80% of rated voltage.
Check vacuum switch. Blower creates vacuum, and the vacuum switch detect vacuum, and signals gas control valve that burner sequence can continue.
Gas control valve can also go bad. Wiring etc can go bad.

Check the filters first, then check for blockage in the return or supplies. An easy way to do this is by putting your hand in front of the vents to make sure accurate airflow is there. Your furnace has limit switches on it that detect heat, and if heat is getting trapped inside the unit to much, you will trip these switches and the blower will just run forever. Then you have to reset it or wait forever. But try those few things first. Hope this helps.

97 Malibu. V6-3100. Starter turns engine, but car

I think you may have answered your own question. I would check to see if the fuel pump is turning on when you turn the key on to the run position. You should hear a buzz sound coming from the gas tank. I would start there.
