Grasshopper question about Gas oven with always on pilot light not working.
Sunray SBP26AA0 and Caloric RBP26AA0. Identical free standing gas stoves with 2 always on burner pilot lights, one always on oven pilot light. This identical model sold under at least 2 names.
Have two units, one oven that works and one oven that does not work.
Both installed maybe 1990's in apartment. Unused for 10 yrs and gas off.
Sunray SBP26AA0 with oven problem.
Gas company turned on gas, lit pilots, oven worked, I saw oven burner turn on. Gas co guy cleaned pilot, "some white stuff on it", he said. Checked for leak with soap water spray.
1 week later pilot on, oven burner not turning on when turning oven knob.
Pilot does enlarge and appears go down to cover the bulb of thermocouple when oven know turned to On. No click after 30+ seconds. No apparent change after 20 min waiting.
I waited 20 min and no turn oven burner turn on. No change. No clicks. I smell no obvious gas.
Caloric RBP26AA0 with working oven.
Checked my working oven. Pilot appears to behave same way as non working oven. Oven knob on, pilot enlarges downward over thermocouple bulb. The difference is after 20-40 seconds I hear a click which I think is gas turning on, see and hear the oven burner flame, flame goes over spreader, and oven works normally.
Do I have problem with thermocouple-gas safety valve assembly? This is a Hyper Wyman 4157094.
Not available at usual parts stores. Available on flea-bay.
If this is the issue, does come off by just unscrewing 2 gas lines and 2 visible screws in the pictures below?
Do I have an oven thermostat problem? Or something else?
Here are pictures of thermocouple safety valve and pilot light.
Grasshopper thanks you.
