My oven is back

The repair man came back yesterday to fix the washing machine again and install the new sensor in the oven. When he installed the new sensor the oven still didn't work. He took the face off, and to my disgust, his younger helper (not him) pulled out two grocery sacks worth of trash from under the burners! He at first asked if I had put the plastic bag in the oven, no it was the rats!!! Aggh! So the oven works again.
