How to troubleshoot aermotor FH50 motor that will not run?

  Timothy YoungAug 2, 2025
  If your Aermotor Water Pump motor isn't running, first ensure the disconnect switch is on. If it still doesn't work, check the fuse and replace it if it's blown, or reset the circuit breaker if it has tripped. Also, examine the starting switch and replace it if defective, after disconnecting the power. Inspect all wires at the motor for looseness, disconnections, or incorrect wiring, making sure to disconnect power before checking and tightening. Lastly, check the pressure switch contacts and file them with an emery board or nail file after disconnecting the power.

Why does my aermotor FH50 keep cycling too frequently?

  Bonnie TranAug 6, 2025
  If your Aermotor Water Pump delivers water but doesn't shut off or cycles too frequently, first, disconnect the power and adjust or replace the pressure switch. Ensure all faucets are closed. Check for clogs in the venturi, nozzle, or impeller and clean them if necessary. If you have a standard pressure tank, drain it to the air volume control port. Inspect all pipe connections for air leaks and replace any leaking foot valves. Lastly, check the air charge in a pre-charged tank using a tire pressure gauge at the valve stem. If it's less than the pressure switch cut-in setting (30-50 PSI), add air until it's 2 PSI less than the cut-in setting.
