Intermatic has had an issue with the main drive gear striping in there timers, I don't know of any best practice repair method for this part, I suggest you replace it or if your not electrically comfortable call a local electrician.
Hope this helps...

Let's review your wiring. There's probably something miswired when you get symptoms like that. Let's work one circuit at a time.
For circuit #1, the incoming (LINE) black (hot) wire is connected to the #3 terminal. The white (neutral) is connected to the "A" terminal. The bare equipment grounding wire is connected to the "GR" terminal (the green screw on the case).
The outgoing (LOAD) black wire to the first set of lights is connected to terminal #4 and the outgoing white (neutral) wire connects to the "A" terminal. The outgoing bare wire to the lights goes to the "GR" terminal. It's best to twist the wires together with a pigtail, wirenut them and connect the pigtail to the "GR" terminal.
Now for separate circuit #2. The incoming (LINE) black (hot) connects to terminal #1. The incoming white (neutral) connects to terminal "A". The incoming bare wire connects to the "GR" terminal.
The outgoing (LOAD) black wire to the 2nd set of lights connects to the #2 terminal. The outgoing white (neutral) goes to the "A" terminal. It's OK to twist all the white neutral wires (incoming _and_ outgoing for _both_ circuits) together with a pigtail that goes to the "A" terminal. Use a red wirenut.
As long as you don't load the 15 amp breaker over 12 amps (this is considered a continuous circuit and it cannot be loaded over 80% per NEC), you don't have to have two circuits if you don't want too. Figure about 1 amp per light as long as the lights aren't over 100 watt. (100 watt lamp/120 volts = 0.83 amps (round to one amp)

T103 has 120Volt clock motor, so we can wire this timer.
T103 timer is rated for 30 amps and 2horsepower and your blowers use 28 amps.
So we're getting close to max on the timer. Hopefully blowers won't all be started at one time since motors draw maximum amperage when they start.
However, you need 30 amp breaker and orange 10 gauge wire for that much amperage >> unless only one blower is turned ON at any given time.
Always match wire size, amperage of breaker and amperage of Load or it will trip the breaker.
If you put 30 amp breaker on size 10 wire it is good. But 30 amp breaker on smaller size 14 or 12 gauge wire is fire hazard.

Look at the basics:
You have 2 cables.
One cable comes from breaker box.
Other cable goes to three 120V plugs (120V is same as 110V).
Each cable has black-wire, white-wire and bare-copper-ground-wire.
How to wire the timer.
Timer has 5 terminals: A 1 2 3 4
A) Cable from breaker box:
White wire from breaker connects to terminal A
Black-wire from breaker connects to terminal 1
B) Cable going to 3 plugs
Black wire to plugs connects to terminal 2
White wire to plugs connects to terminal A
Ground wires connect to green ground screw.
Terminals 3 and 4 are not used in this case.
Here is a wiring diagram that shows 120Volt from breaker box and 120Volt going to Load
