Thermador prsg304 oven thermostat for gas bake burner and gas broiler. Gas valve should receive 3.03 to 3.3 vac but is receiving120 volts from thermostat. Thermostat receives 120 volts input. Does thermostat reduce voltage to 3.03 to 3.3 prior to sending it to the gas valve.
You should do an amp draw on the igniter to see what amp draw you are getting. The igniter should be dropping the voltage to the gas valve as it has high resistance. Once the resistance of the igniter falls enough to allow voltage through it would allow 3.2 to 3.6 vac to get to the gas valve. When testing the voltage at the gas valve you do not want to check to ground you will check across the leads of the gas valve and with the burner turned to the on position check for the 3.2 to 3.6 vac. Also if you do an amp draw on the igniter it should read 3.2 to 3.6 amps. If you are not getting this from the igniter or from the gas valve then the igniter is bad. If you get the proper amp reading and the proper voltage reading then the valve is bad and would need to be replaced.
Large electric oven thermostat needs to be replaced and part is no longer available??? Can you locate this part? This is a dual fuel unit.
Answer Hello Jim! Unfortunately, the main oven thermostat 486945 has been discontinued and is no longer available. The small oven thermostat, part number 00487259, is still available for purchase. Thanks.
