Response to I have a 2 timer , 220V intermatic (T0404R (?)) timer controlling my 2 speed pump. I turned on the pump via the timer, and get a constant Humming sound from the timer. I disconnected the motor, and still get the hum at the timer. Should i replace timer? also, the Circuit breaker has 2 pairs of breaker feeding timer, and 1 breaker is not fully "clicking" on. Is it possible this is reducing the current and causing the hum?
