Sta-Rite DS3HF 1.5 HP Pump Motor Hot, Won't Start: Check Voltage Selector & Motor Health

Pump Motor Hums, Gets Scorching Hot: 115/230V Selector or Bad Motor

Pump start relay clicks, motor gets 230V (or 115V) but won't spin. Motor extremely hot after 20 min off.

Check Voltage Selector Switch

Motor has a 115/230V jumper or switch. Must match supply voltage. Wrong setting = instant overheat.

Verify Supply Voltage

At motor terminals: measure actual voltage while relay engaged. Must match selector.

Motor Quality Alert

Recent motors (last 12–18 months) have higher failure rates—copper cost cuts. Seen 3 DOA in a month.

Action

1. Confirm selector matches supply. 2. If correct and motor still won't start → replace motor. 3. Consider upgrading to a name-brand motor (Century, AO Smith, Baldor).
