Amana furnace main burner intermitent

Honeywell is a controls company and makes a variety of auto-pilots. If this is a no spark problem,does the lead from the igniter go to a big PC board or a module. If a module, check voltage to the spark module or thermostat voltage to the ignition module. If it comes from a large board, the board may be bad. I'll need more Info. if this does not cover it for you.

Clean pilot , replace thermo couple if it looks burnt out clean flame sensor

There are two sensors on the burner box of the furnace that control the fan. One tells it when the furnace has warmed up and the other tells the furnace has cooled down. If it blows before the box is hot enough, the limit switch is bad. Any heating and cooling company can get one for you and you can probably switch it out yourself.

It must be lighting once and a while. Most of the time if buner refuses to light the furnace will lockout. There is flame rod in the burner that needds to have the flame touch it to prove the flame. Take some sandpaper and clean theis rod and try it agian. But that sounds like the problem. Call back if you have more problems be glad to help Rus

flame rod sensor

check the pilot gas pressure, might be too weak and blowing out when the blower starts, the clicking noise is the gas valve shutting down when it detecks no pilot flame, that park is normal.

sounds like the high limits tripped

the first blower you hear is the inducer motor it pushes the exhaust out. sounds like abad gas valve.do you have a standing piloit light or is it eletronic ignition. if electronic and there is no glow you have a bad ignitor

Hello Genna,
I am not a furnace guy but I may be able to give you a few ideas of things to diagnose the problem and get it resolved. First off, I assume you have a thermostat that you use to to turn your heat on. If it is a generic ( meaning : non programmable model) then you should be able to try this simple test. Remove the cover ( typically they snap on) around the thermostat so you can see the control mechanism inside. You should see few skinny wires ( similar to those used on a telephone wire) solid copper in various colors.. When you rotate the dial on your thermostat to call for heat, there is a small glass vial that has a drop of mercury ( which is electrically conductive) in it that makes contact and shorts two control wires together ad that is what calls for heat on your furnace. When the temp inside the room where the thermostat is reaches the tempertaure you requested, the bimetal mechanism either contracts or expands to reposition that glass vial to shift the mercury off the contacts and your furnace shuts off... That is the basics behind how your thermostat and furnace work ( generally speaking) If you can identify the two wires inside the thermosat that are shorted together when that vial of mercury shorts them inside it.. you can temproarily unhook them ( they are low voltage.. normally 24 Volts or less) so no worries about getting ashock or anything.. and short them together for a minute or two.. by doing that... your furnace should turn on and heat should flow.... Once you start your furnace this way.. unhook these two wires and your furnace should shut down .. It may take a minute or two ( depending on the control for it) If it doesn't..then your problem is on the furnace side and you may need to get the furnace control system serviced or replaced.. if it does shut down, then your problem is your thermostat and thats a simple replacement.. Also.. make sure the thermostat was properly leveled on its base.. The position of the thermostat ( meaning level) will dictate when that mercury makes contact and your furnace switches on.. OK..I tried to explain the works of this to you but here is a link to a Honeywell site that explains it in simpler terms.. The part about shorting the two wires together and then opening them will aid you in identifying where the problem actually is.. here is the link: http://homerepair.about.com/od/heatingcoolingrepair/ss/thermostat.htm

Hope this helps you more than confuses you..
Regards

I would guess from the info provided that you only have two wires going to your thermostat which would explain why the fan switch doesn't work on the thermostat. You can bypass the thermostat as a first step in troubleshooting. After that it depends on the type of furnace, standing pilot or electronic ignition...
