Hello,
My mother has an Amana Big Oven ACF3325AC and the cavity light does notwork. I turned off the power and replaced the light fixture and still nothing.(I confirmed the bulb is good). When I pulled the oven out, I did notice that one of the wires that connect to the light fixture looked a little burned. The"Oven Light" button on the main display does light when pressed. I am willing to replace the display/computer if that is the problem but I'm just notso sure. Any help would be appreciated. Thank you!!!

Hi. Unfortunately, the clock/control board is not available any longer. If you already replaced the light assembly Part number: 31823701
all you can do, is to check the wiring to the light. Simon.

Hi.
You will be checking the continuity, not the voltage. So, unplug the range, remove the wires from the light socket, set your meter to the ohm scale.
Place one probe to each end of the wire. You should read less then one ohm resistance. Otherwise, the wire is bad.
Simon.

Simon. Simon, Thanks for the reply. Sorry I'm not too good at this. I sort of understand continuity testing, but there were 2 wires connected to the light fixture each going to different points on the oven (I believe one was going to the clock/computer and the other one going to the bottom where the main power cord for the oven was.) Do you mean just test one wire from the back of the fixture to where it connects to the clock/computer and test the other wire from the back of the fixture to where it connects down by the main oven power cord? Thanks again.

remove back of range to gain access to fixture. you will have 2 wires on the fixture. set volt meter to read at least 120 volts. plug in range, turn lite on, place leads on fixture wires. if you have 110 to 120 volts, the board is good and you have a lite fixture or bulb problem. if you do not have voltage, take the board off and check for broken solder joints, resolder if necessary. good luck

Hi.
You should test them both from the light to the control board.
If you are familiar with the testing, do the voltage test.
With the range plugged in, turn the oven light on at the clock/control and check if there 120 Volts AC between the two light socket contacts (with wires on).
If there is proper voltage present you need to check the light bulb and socket connections.
If there is no voltage, then the control is bad.
Simon.

Simon. Simon, Okay thanks. It is a new light fixture but I will test the voltage, which as you indicated, should help to determine if the control board is bad. I confirmed the light bulb is good so that leaves either the wires, control board, or fixture (which is new but you never know). Thanks again....this is a big help!!!!
