Could be a bad timer contact
Could also be a bad connection
Cut power to the unit
Open up your control console
Check the wires for any indication of overheating etc.
Then one by one disconnect then reconnect the wires to the timer and all switches and interconnections.
If one of them comes off too easy crimp the female end down a bit so it is tight
Put it back together and give it a shot
