F1 error
Here is some wisdom for understanding F1 fault codes.
In some models, there are subcodes that make diagnosis even easier.
Here's a simple explanation of what's going on and how to troubleshoot:
The F1 code indicates that:
a. The electronic range control (ERC) is sensing heat in the oven when in a time-of-day (i.e., not cooking) mode.
b. The ERC is receiving information to run multiple heat functions simultaneously.
Although different components (depending upon the model) could generate the code, simple and straightforward testing using your ohm meter is all you gotta do to test for it.
1. Check the oven temperature sensor. The oven sensor has to be within spec or it will cause the F1 code.
As an example of being out-of-spec, the ERC will generate an F1 fault code when the sensor shows 1650 ohms during a time-of-day mode.
This is equivalent to 350°F in the oven.
The resistance isn't high enough to generate an F2 code (runaway temp) or an F3 or F4 code (shorted/open sensor circuit).
The ERC monitors the sensor circuit after a heat cycle and expects the resistance to drop back to 1050-1100 ohms.
The fault code is generated when this doesn't happen. Checking the sensor circuit means also checking the harness,
harness connections and the sensor itself.
2. If the oven sensor circuit checks okay, then turn your inquisitive eyeballs to the touchpad.
If the range has a separate touchpad/keyboard, the keypad may have moisture that is shorting several circuits simultaneously.
If the F1 code is given immediately (instead of during or after a heat cycle),
remove the ribbon connector from the touchpad to the ERC after clearing the F1 code. If the F1 code does not return in five minutes,
then cast a suspicious gaze upon the touchpad/keyboard. Shorts may be caused by using an ammonia-based glass cleaner.
The touchpad surface will absorb ammonia-based cleaners that are sprayed directly on the glass surface. When heat is applied,
the surface material can break down causing shorts.
If you're gonna use ammonia-based cleaners on your control panel, then you should spray it on the rag and then wipe the touchpanel
-don't spray directly onto the surface of the touchpad.
3. On Amana ranges with a rotary temperature dial, be sure that the knob is in the OFF position when performing tests.
4. If these tests all check good, then replace the ERC.

Slight GAs odor
Most all Gas Companies will check any apliance for leaks for free. Just tell them you "smell gas" and thats all.
Any repairs to a Gas appliance should be done by a Licensed Contractor or yoiur local Gas company.
I have repaired Gas appliances for years and NEVER ADVISED a CUSTOMER to touch anything involving GAS. It is not worth the RISK.
Be safe ...

Thermador model GGCV30 gas cooktop
The flame spreader in the middle of the hob has a small hole that directs as jet of gas to the igniter. Put it in a pan of water and dish soap and gently heat it to almost a simmer. Be careful, it will want to boil over. Leave it to cool and and rinse it well paying attention to the holes in the edge. Blow it dry and try again.
