Coffee not brewing but light is on.

Probably the thermo cut-off device is stuck in "open" condition a safety component used to prevent over heating and potential fire. It's in the internal wiring to monitor the temperature where the water is brought up to boiling. It triggers every time as you finish brewing, to cut the flow of electricity to the heating coil. It now must be replaced which an experienced do-it-yourselfer can do, but you must find the right temperature "thermo-disc" (usually rated to open at about 220F/105C) to wire in. Unfortunately I've never seen one with a simple plugin feature. This is NOT an uncommon problem as a coffeemaker ages.

Mine was coffee maker bout 6 mths old but mr coffee replaced it with brand new unit if now we can figure how to program everything on it thanks Mr Coffee

Try this from the troubleshooting guide.
