Hi sallysue5928 - How long was the delay start set to? Typically the delay time selected will be displayed as 30, 60, or 90 minutes or 2 through 14 hours. However, try reprogramming the unit by unplugging it or flipping the household circuit breaker off. Wait approximately ten minutes and restart unit. If it was unsuccessful then unfortunately you will have to wait till the time of the delay start cycle that was selected.
The 4½
minute interval can be changed to 1½, 2½ or 3½ minutes as follows:
Press and hold the Lock button until the light blinks (about 10
seconds). A single blink indicates the the time is reset to 1½
minutes. Repeat the procedure and the light will blink twice,
resetting the timer to 2½ minutes. Repeat again for a 3½ minute
interval, etc., up to a maximum of 4 blinks and 4½ minutes.
