Compressor shorted to ground. (will need a new compressor).
Dirty furnace filter
Tripped AC Breaker (If your AC is not coming on I would suggest turning the breaker completely off and back on again to make sure the breaker is on. Do not touch anything metal on your circuit breaker box for safety).
We have this questions asked many times over the years and I want to post my response to this frequently asked question: I am so sorry to hear that you have spent all this money and still do not have a furnace and air conditioner that are working properly! I have this problem asked many times over the years and my answer is: I would strongly recommend that you have your HVAC contractor do a Manual J Heat Gain and Heat Loss calculation on your home before installing a new furnace or doing any other work. We are required here in Louisville, KY to submit a Manual J calculation to the Housing Department, Code enforcement before a permit will be issued to start a new installation. Without the Manual J calculation, it would be a guess as to what size equipment needs to be installed and this is why many people get the wrong size equipment. Requiring a heat gain, heat loss calculation protects the homeowner from getting the wrong size HVAC equipment installed. Most companies have a Manual J computer program where they enter the required information like the home’s orientation (facing north, south, etc.) the amount of insulation, window types, door types and all surfaces that gain or lose heat and more. The computer program will figure the amount of heat loss and gain and tell the contractor what size HVAC equipment needs to be installed. I would recommend that you get this Manual J calculation completed for your home so you know for sure that you are getting the right sized HVAC equipment installed. Even though it is a pain and extra expense for the homeowner and contractor this insures the right size equipment is installed and is invaluable for protecting your energy bill and comfort.

Question: I have a Super Quiet 80 Achiever Series by Rudd furnace. It works great when it wants to. Intermittently it will shut down at night and we have to wake up cold in the morning. Troubleshooting reveals the first burner of the 3 always lights like it is supposed to, but the other 2 don’t always follow suit. Sometimes they light off and other times they try twice , fail , and the furnace shuts down till we reset everything and start over. Service tech came out, cleaned the ignitor, checked everything he could think of and it seemed to work well while he was here. He said we could possibly have a low gas pressure problem. I guess I’m looking for some professional input before calling him back and start the high priced guessing game again. I would really appreciate any input you could give me. Thanks in advance !! Joe
Answer: Hi Joe! Sorry to hear that you are having trouble with the burners not lighting all the way across sometimes. This probably occurs most often when the furnace is cold and trying to light and start. If the service tech did not already do this I would suggest that you turn the furnace and gas off, take the burners out and blow them out with compressed air and use a wire brush to clean them out on the outside. I would unscrew the gas orifices and blow them out with compressed air. I would suggest either cleaning or replacing the flame sensor while you have the burners out. If you need part numbers please send me your furnace’s model number and serial number to our email address:email@example.com and I will give you the part numbers. If you are still having problems with the two burners not lighting properly I would suggest adjusting the gas pressure up on your gas valve. I would suggest turning the adjustment screw counter-clockwise 1/4 a turn and test to see if this helps. Be ready to turn the furnace off with the power switch if the furnace does not light right away because if the gas valve is not adjusted properly it can cause delayed ignition (small explosion) and this is not good. I have seen delayed ignition blow furnace doors off! There is a good Youtube video on how to properly adjust gas pressure on the following page: https://www.youtube.com/watch?v=xvQabz6d_4g Thanks to ACServicetech for making this great video! Your problem sounds like either dirty burners or gas pressure on the gas valve set too low. I hope you can find and fix this problem soon! Steve
