Hello Jake,
I have been troubleshooting my Amana range all day with no results and thought I would look on Internet for help. This range has worked 10yrs with no trouble up till now.
I have a problem only with the range operation. The clock, timer and surface burners work normally. No Fault errors display at any time. I can force an F3 fault by unplugging the RTD temperature sensor.
Problem
When setting the timer/controller for either bake, broil or convection range operation, the settings enter normally and the display shows the desired temperature which will advance with the Slew arrows, the set temperature (example 400 deg F) is first shown, then "170 Pre-bake", then "On" displays (convection motor starts if in convection mode) for about 5 seconds and then everything goes off except the clock-no audible signal.
Initial Observations
The ERC ground clip (J2 pin1) was improperly installed by the factory and loose on the chassis under the ERC. No improvement was found when I put it in place.
Checks
1.) I first checked all relays on the Xfmr Relay board for motion using the "Quick Test" "Press and hold "cook time" pad for 5 secs after power up method. All relays work and momentarily deliver the appropriate voltage to their respective load.
2.) Voltage check at J1 on the Xfmr Relay board shows terminals J1-J2 = 29Vdc, J1-J10=23Vdc, J1-J12=23V full wave pulsating DC(I believe this is right rather than the 11.5Vac shown in Amana Manual RS2320001), J1-J13=23V full wave rect dc - again I think this is right rather than the 12.5 Vac shown in the manual and J1-J14=23Vdc. Both these voltages are derived from the isolated transformer winding on the Xfmr/Relay board and referenced to ground from the full wave bridge rectifier located in the ERC module. These voltages all seem normal to me.
3.) When energized, the Double Line break relay-K6 delivers full 240Vac to the BROIL, BAKE and CONVECTION COOK relays.
4.) Oven High Limit Switch is closed passing current to the Double Line break relay at all times.
5.) All bake modes fail when the Double Line break relay-K6 looses its drive after about 5 secs when ERC controller shuts it off.
Do you know if there is some peculiar mode the ERC could be stuck in? I tested it for "Child Lockout". Child Lockout turns on and off normally. I see it has a 12 hour turn off protective feature which seems to be off. I don't see a "Sabbath mode".
I don't think the "Watch Dog Timer" could have stopped or it would show the F1 error code. All of the pads on the "touch control" switch work normally which indicates the strobe interrupt is working and corresponding controller inputs are working.
The Amana troubleshooting manual diagnosis is a failed ERC board but it is hard for me to believe it has failed when so much of it is working properly.
Thanks for any help you or your forum members might supply,
Bill
