Where is the auxillary limit on a rudd urka gas furnace

There should be a small set of screw lugs on the electronic board in the furnace. Look for a red wire that comes out of the transformer and follow it to find where the 24V connections are.

to carmelmontgo; do you have a smart gas valve sometimes the wire connections get loose. remove wire connector then reinstall. also cleaning a flame sensor will work if the flame sensor is good. I would check the ground connection sometimes contaminated with rust. also I would check the gas pressure with a gas manometer...my email is [email protected]

Hi,

If the Igniter is not glowing, then the gas valve would not open to push out the gas. This indicates a Weak Igniter and you need to replace that.

Let me know, if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Well first you want to verify that there is gas pressure coming from the connector. Turn off the valve and disconnect the connector. Then turn on the valve for 1 second and back off. You should get plenty of gas flow. Be careful doing this!. Then inspect the opening at the adapter to the control. There is a screen inside there. Make sure the screen is clear(not plugged with pipe dope,lint ect). When the igniter reaches the 2200 degrees you should hear the gas solenoid valve click open releasing gas. If you hear it click and no gas is released you will need to inspect the burner orfices. The orfice has an extremely small hole and there is a posibillity that they are plugged with debris. You will need to use a very small wire(like a tie strap) and insert it into each hole and see if there is anything in the orfice. If you do not hear the gas valve click then it might not be getting the signal it needs due to a weak igniter or flame rectification sensor. Does your furnace have a stand-by pilot that is lit by the hot surface igniter or does the igniter directly light the burner assembly?
