Amana 90 furnace - 1 blink error code


Furnace has an error code of 1 blink. Amana 90 series 92% AFUE.

Will work if the thermostat is turned off then back on. After the room reaches temp the furnace shuts off like it's supposed to but then flashes an error code of 1 blink and will not restart on it's own. Please assist - can not find the manual.

Not much info to go on, but lets look at a few possibilities. Your thermostat could be turned to the ?Fan On? setting, make sure you put it in the ?Auto? mode. Or it could be bad, or there could be a short in the wiring. Open up the access panel on your furnace. Lets eliminate the thermostat from the equation by disconnecting the red, white and if you have a yellow wire at the furnace. Mark down which wire went where. The furnace will have a door safety switch that will have to be taped temporarily closed to test the furnace. With a short piece of wire (2-3" long), strip off 1/2 inch of the insulation on both ends. Secure one end on the R terminal where you removed the red wire from your thermostat. Take the other end and touch the G terminal on the same electrical board. Your fan will start. Don't worry about an electrical shock, the voltage is only 24 volts. Now with one end still attached to the R terminal, touch the W terminal where the white wire was attached. The furnace will now try to fire up. Hold it there until you see that it did start. If you did this and had success, I would say it was your thermostat or the wire going to it. Last resort would be a bad control board. If you want, you can do test your thermostat wiring by removing the thermostat from it's mounting plate. Put all wires back where they were on the furnace. Make sure the access door is back in place and secure. Take that same jumper and jump across the red and white wires on the mounting plate. Again the furnace should start up. Have a helper jiggle the thermostat wires where accessible when the furnace is running and see if it remains on or shuts off. If everything checks out, replace the thermostat. Good Luck!

A Make and Model number of the furnace not the thermostat will help but I can walk you thru the operation of a typical furnace. It sounds to me that the burners are igniting properly but the flame sensor is not sensing the flame and shutting down the system. You will need to find the sensor and clean it and check the wire from it to the control board. Typically, the flame sensor is found at one side or the other of the burner box. It is a small probe that the flame hits. Depending upon your model it may have a small wire attached to it leading back to the control. Or it may be part of your auto-pilot assembly. ? At any rate, you will need to get to it and very delicately brush it off. Then inspect the flame channel. This is a trough area where the flame travels to ignite all burners. Over time, they tend to fill with rust and debris. Take a small screwdriver and run the blade down the trough. Inspect the wire that goes from the flame sensor to the control board. Make sure it is not frayed or broken or shorting out and that the connection at the board is good.

Beyond that, it's time for a technician to come.

Let us know the Make and Model of the furnace (found inside the furnace cabinet) and maybe we can help you further.

Turn off breaker. Turn it back on. If furnace is completely dead still, change your transformer. It's cheap..

SOURCE: Furnace doesn't reach desired temperature

On the thermostat if its a manual on then pop the cover off and look for a small dial with numbers on it. Take and move it tpoi a higher number than whats it is set at. Its called a heat anticipater and is supppose to make it so that the unit does not oveshoot or under shoot like what your experiencing. If its a digital oine then you are going to have to configure the setting in the insdtallers menu.

Induction fan comes on ignitor wont ignite


If the igniter turns orange and the gas fires for only a second or two then your heat sensor needs to be cleaned with sand cloth, if it does not turn orange then your igniter needs to be replaced.

Amana furnace won't start


Go to the thermostat and switch the fan to "ON", if the fan runs you have both high and low, 24 volt control voltages, go to the unit and look for a flashing code by the blower assembly, there will be a tiny port to see through on the lower door of the furnace, this will give you any codes telling you what has failed.

Is there an on-off switch on the furnace?


Generally, if there is not a breaker within line of sight, there will be a toggle single pole switch that will shut the furnace off. The blower cabinet will also have a door switch.

Furnace computer won't let furnace light


What is the model number? I have an SLP98 (installed on 11/29/2011).... and if I take the cover off the front of the furnace the panel that has the fancy "Lennox" badge on it) you will see two clear round windows about the size of a half dollar (one high on the furnace box and one lower on the blower box.) If you look downward into the window on the blower box you can see a red LED display that will sometimes flash error codes like E228 (one character at a time). If your model has something like this, let me know. I've done some DIY fixes recently out of necessity....and their easy.....and several technicians confessed they didn't know much, if anything, about the newer high effieciency Lennox gas furnaces.

Furnace runs but won't ignite.


Error code 12 is blower on after power up. Meaning: after you turn on power to the furnace for aprox. 60-90 seconds the blower will run. The blower should then shut down and the furnace should go through the start up process, providing that the thermostat is set for and calling for heat. If the furnace fails to start after blower shut down there should be a new fault/error code. However if the blower continues to run longer then 90 seconds and continues with the same fault code more then likely the circuit board is bad. Please let me know if this was helpful and give me a rating. Good luck.
