To turn off the timer on a Carrier 40GRQ:

- To cancel TIMER ON: If T-ON is active, press the “T-ON” button to cancel it.
- To cancel TIMER OFF: If T-OFF is active, press the “T-OFF” button to cancel it.

When the ON or OFF light is on under the time on the remote, it indicates that TIMER ON or TIMER OFF is currently set and active.
