viking oven not receiving gas after catch tray removed/cleaned
I rent a house which has a viking range/oven. Everything was working fine when I decided to clean the large stainless steel catch tray. I carefully pulled out the grease catch tray directly below the range and above the oven. I saw that wires hang above the tray so I was careful to remove and insert it carefully and gently. After I put the tray back in the oven does not get gas when the knob is turned on.
When the oven is turned on, the red light turns on by the knob but no sound or smell of gas and I do not hear any ignitor attempting to light. Honestly, I don't remember ever hearing the ignitor click when turning on the oven in the past.
When the broiler is turned on the red light beside the knob turns on and the ignitor glows in top of the oven, but again no sound/smell of gas and the broiler burner does not light.
All burners on the stove ignite and work normally.
The repairman wants $200 just to come to the house, plus any labor/parts cost on top of that.
Does anyone have any idea what is going on?
Any help is greatly appreciated.
