If you were experiencing a failure just after a heating cycle but not on a cold start, I would suspect an electrical component failure. As the component cools, it makes contact and allows the furnace to operate. This will change and not for the better. Depending on what your system has for electrical components, I suspect either a relay or transformer. At any rate, get a technician in front of it so he/she can diagnosis it under both cold start and hot start conditions. It will help if you turn off your system so it will be cool when the tech gets there.

York furnace code 7


The error 7 shows that the gas failed to ignite. That is because the sensor does not sense any flame. This can be because the sensor is dirty. You should look in the area of the jets for a wire that may be purple in color. It attaches to a bare metal probe that is shaped like the letter L This probe extends into the path of the flame from the jets. When it detects flame it tellls the controller that everything is good. When it gets sooty or dirty from use it cannot detect the small electric currents that are present. Clean it with scotchbrite. Error 7 means that the furnace is locked out and wont restart for an hour. You can shut the power off and turn it back on to reset it.

check the distributor advance unit pull the pipe off and then **** on advance unit to see if the diaphragm moves and stays in ,because the membrane goes then it will not start ,so you advance the distributor and it will start ,but once it gets hot the engine will not start unless you ****** the timing that bit .then when you do that it will not start when cold .

Heater won't heat very long


there isnt a pilot if it has jets , it has a Hot surface ignitor. you should see a glow and then the jets light , if its running for a few min it may be overheating, have you changed the filter recently? you should also have a flash code you can locate when the furnace shut off and is no longer doin what its supposed to look thru the bottom door peep hole and watch for a series of red flashes. if you remove the cover after retrieving the flash code there will be a chart on the inside of the cover that will tell you why the furnace is shutting off. by the way the model # you gave is for the A/C coil above the furnace, not the furnace.

Laars Lite 2 LG - pilot light will not stay lit. As long as you hold down the pilot light once it is lit it stays lit but when I turn the nob to the "on" position (release the pilot light button) the flame...


It sounds like a thermocouple has gone bad. this is a very common problem with gas powered things ie; water heaters, furnaces, hot tubs. The telltale sign is when you release the pilot light button it won't stay lit. This is a safety feature and is relatively inexpensive and easy to repair.

My AC unit wont blow the cold air.


if the ac outside is working, but not the furnace, means there is a control problem with the furnace, check wires in the furnace, make sure there is a blower wire plugged into the contact marked cool on the control panel of the furnace

Gas furnace wont stay lite


I'm a little confused by your terminology. You are saying you have a pilot lite and electric heat strips? Are you possibly meaning burners? Is the heater running for 2 hours straight without shutting off? how cold is it there? Lastly what temperature do you have the thermostat set at and how close does it get to the temp. before it shuts off?
