How many watts is your timer rated.Also sounds like bad ballast.

Or... You could be just exceeding the load of your timer....
Your balast is rated at 1000 watts output...
What is your timer rated at? Look at the electric name plate, all electric items with a UL label have one...
Plug timer direct into power sorce...
Check every 5-10 minutes... if it doesn't cut out, it's timer....
Sometimes, power equipment uses a little more power [amps] when it gets older...
What worked fine yesterday... could blow out today....

Make sure you clean the lamps off [your finger's touch them?] after you re-install... something like Rub Alcohol wipe..

I have a heavy duty timer and when I plugged my fan into it with my ballast it blew it. Now I run the fan off a strip and the ballast into the timer. No problems so far.

thanks for the advice my timers says on the back of it this 125v 15 amps 1875 resistive 10 amps 1250 watts tungston i only ran my ballast of this because i was afard of overload idk ipluged it in to just the outlet today it seems to still work idk
