Grill system and method for detecting movement when motor is “off”

1. A method of detecting movement of a first platen assembly of a grill while a motor is off, the method comprising: shorting a motor coil of the motor operable to move the first platen assembly with respect to a second platen assembly so that back electromotive force (“EMF”) causes current to flow in the motor coil in response to mechanical movement of the first platen assembly; and measuring the current to identify a relative position of the first platen assembly with respect to the second platen assembly of the grill.

2. The method as recited in claim 1 , wherein identifying the relative position of the first platen assembly includes identifying a latch failure.

3. The method as recited in claim 1 , wherein identifying the relative position of the first platen assembly includes identifying an over travel condition.

4. The method as recited in claim 1 , wherein identifying the relative position of the first platen assembly includes measuring movement of the first platen assembly.

5. The method as recited in claim 1 , wherein identifying the relative position of the first platen assembly occurs while a spring mechanism is biasing the first platen assembly.

6. The method as recited in claim 1 , wherein identifying the relative position of the first platen assembly occurs whenever the first platen assembly is not moving.

7. The method of claim 1 , wherein the first platen assembly is an upper platen assembly.

8. The method of claim 2 , wherein the first platen assembly is an upper platen assembly.

9. The method of claim 3 , wherein the first platen assembly is an upper platen assembly.

10. The method of claim 4 , wherein the first platen assembly is an upper platen assembly.

11. The method of claim 5 , wherein the first platen assembly is an upper platen assembly.

12. The method of claim 6 , wherein the first platen assembly is an upper platen assembly.
