The range top has two of four burners that cycle on and off intermittently to continuously simmer the food. After the burner has been on for a while (heat's up) and then I turn it off, it will not reignite until the burner cools down. It is not a problem with the spark igniter as it continues to spark. It is the gas valve that does not open. Once the cool down occurs the gas valve and the intermittent cycle works as normal. Is it the solenoid, the valve or the control board? Thanks. The valve part number is AP2830383 I think.
Answer Hello Peter,
Turn the two sequence burners to “HI” (non-sequenced mode). Check the voltage on the Spark Module Input Terminals SW1, SW2, with respect to Neutral (N). The voltage should measure 120 VAC. If it does, check the spark module. If it doesn’t, Check voltage on Simmer Controller, Seq 1 and Seq 2, and line with respect to Neutral "N". Voltage reading should be 120 VAC. If it does, check the wiring. If it doesn’t, Turn Front Extra Low Burner Knob to "HI" and check voltage between Pot 1 and 120V line at the simmer controller. Voltage reading should be - 2.2 VDC. Turn control to Low and verify no change in voltage. Continue turning to Extra Low. Voltage should change to - 1.2 and increment down to Ø volts. Repeat this process for the rear burner. The voltage reading between Pot 2 and line should function the same. Warning: Both Pot1/Pot2 and Line-5 are carrying 120VAC. If the readings are correct, check the spark module. If they are not, replace the simmer control. If replacing the simmer control leaves an issue present, check the wiring between the simmer control and the potentiometer. If no wiring issues are located, replace the potentiometer.
To check the spark module: Turn both burners on high and check voltage on the simmer control between each Solenoid. Voltage should read between 85 and 110VDC. Repeat this process on Solenoid 1 and Solenoid 2. If the voltage doesn’t read correctly, replace the simmer control. If it does, Check the voltage at each solenoid terminal. If it reads 85-110VDC, replace the solenoid. If it doesn’t, check for a problem in the wiring.
Is there an high/low adjustment screw on these valves?
Answer Hello Bill. No, there is no adjustment screw according to the service manual. Hope this helps.
