My swimming pool's pump stopped working, the motor hums and the shaft will not spin. This pool motor repair guide for Long Beach names the failure mode and the cost band. It covers six motor faults, a diagnostic flow, brand notes, and the DIY-vs-pro line.
It's hard to find a company you can fully trust on a motor diagnosis. Adam's Pool and Spa Service publishes cost bands and names the failed part before any tools come out.
Run a five-step motor check. Kill power at the breaker. Listen for hum, screech, or silence at startup. Look for water under the seal plate. Spin the impeller by hand. If the motor still fails, call a licensed pool tech.
The pump is the full assembly. Housing, impeller, shaft, motor, and capacitor. The motor is the electric portion that drives the impeller.
Most motor-only repairs leave the housing and impeller alone. A motor swap costs $480 to $900 installed. A full-pump replacement costs $700 to $2,200.
The savings on a motor-only swap is $300 to $1,300. That is real money when the volute and impeller still run clean.
Six symptoms cover almost every motor-repair call we run in Long Beach. Each card names the symptom, the most likely cause, what you can safely check, and where the cost lands.
Worn motor bearings, accelerated by Long Beach salt air. The whine starts subtle, then becomes metal-on-metal inside thirty days. Safe homeowner check, none. Bearing failure means a motor swap, $480 to $900 installed.
Failed start capacitor in nine cases out of ten. Power reaches the windings but start torque cannot kick the shaft. Safe homeowner check, kill the breaker and spin the impeller by hand. Capacitor replacement runs $180 to $280.
Most often a worn shaft seal. The seal sits between the wet end and the dry motor canopy. Safe homeowner check, confirm the leak is from the seal plate, not a cracked union. Shaft seal replacement runs $220 to $380.
Burnt windings, a wet canopy from a leaking shaft seal, or a shorted VS drive board. Safe homeowner check, none. Stop resetting the breaker and call a tech. Motor replacement runs $480 to $900.
Pentair EE, F1, or Hayward ER1 codes almost always point at a failed drive board. The motor is silent, the pad screen blinks. Safe homeowner check, photograph the code. Drive-board replacement runs $500 to $1,100.
Failed run capacitor, a tripped thermal overload, or a failed drive board on a VS pump. Safe homeowner check, confirm voltage at the time-clock or breaker. Capacitor swap runs $180 to $280. Drive-board replacement runs $500 to $1,100.
Run these in order before calling a tech. Most homeowners can finish steps one through four safely. Steps five and six need a licensed pro.
Look for puddles, rust streaks under the seal plate, or a hot motor canopy. A wet canopy is a red flag, kill the breaker now.
Whine, hum, silence, or thermal cycling. The noise points the motor diagnosis.
On a variable-speed pump, photograph the screen. Pentair, Hayward, and Jandy each publish a fault-code key.
Power off, lid off, reach through the basket throat to spin the impeller eye by hand. Grinding equals bearing failure.
A licensed tech reads voltage, amp draw, and start-up amperage. Capacitor, drive board, and winding faults all show on a meter.
If steps one through four did not surface the cause, or if the breaker trips, call a licensed pool tech. Adams answers the line and quotes a written diagnostic before any work.
The honest answer is age plus housing condition. Motors last 8 to 12 years on a residential pad. Coastal pads in Belmont Shore and Naples Island run on the short end.
A motor-only swap makes sense when the volute is uncracked and the impeller is clean. The pump should be under 10 years old. Replace the full pump when the volute is chalky, the impeller is cracked, or the pump is past 12 years.
California Title 24 requires variable-speed on replacement pumps over 1 horsepower. Read the math at repair vs replace pool pump. Also see variable vs single-speed pool pump.
Pool motor parts age on different clocks. Six wear curves we track on Long Beach pads:
Adam explained every piece of equipment to long-tenure clients. The reason customers keep calling is what happens past the basket lid. Six things a Long Beach motor tech does on a call:
"My swimming pools pump stopped working. I was looking for a reliable and honest technician, luckily I stumbled across Adam. Booking was easy, he showed up on time and within a couple minutes or so he had figured out and corrected the issue. He also covered the fee since the issue was minute."
"Adam's Pool and Spa Service was extremely helpful in upgrading our pool pump. They helped us source the best price and they were readily available to do the install. I also use them for monthly pool service. Our pool looks great!"
"Adam's Pool and Spa Service service was communicative, competitively priced, timely, and professional at every step of my pool filter and salt water chlorinator install. Adam explained every piece of equipment and how to maintain it in a way that I could understand."

You see a written quote first, with a line-item number on parts and labor. If the fix is a $200 capacitor, that is what you pay. If the volute is cracked or the pump is past 12 years, we say so.
We call back within 24 hours on every voicemail. For dead-motor emergencies, most Long Beach calls get an on-site diagnostic the next business day. Trucks carry common Pentair, Hayward, Jandy, Sta-Rite, Century, and A.O. Smith parts, so most motor repairs close on the first visit.
A bearing-driven motor swap runs $480 to $900 installed. The motor part itself runs $300 to $650. Price varies by horsepower, mount style, and brand. Labor runs $180 to $250, including a fresh shaft seal at the same time.
8 to 12 years on a residential pad, shorter on coastal yards in Belmont Shore, Naples Island, or Alamitos Beach. Salt air pits the motor shaft, dries the seal lip, and corrodes copper windings inside the canopy. Inland pads in Lakewood and Bellflower hit the long end of that range.
Most often a worn shaft seal between the wet end and the motor canopy. The seal lip dries out and water drips down onto the seal plate. Caught early, it is a $220 to $380 seal swap. Caught late, water hits the windings and you need a full motor replacement.
Century, A.O. Smith, and Regal Beloit replacement motors for single-speed units. Pentair (IntelliFlo VSF, IntelliFlo3, SuperFlo VS, WhisperFlo). Hayward (TriStar VS, Super Pump VS, MaxFlo XL, EcoStar, UpRated). Jandy (FloPro VS, ePump, Stealth). Adams is Jandy Certified and a Pentair Expert Installer with motor parts on every truck.
Stop running it. A grinding bearing destroys the canopy in days. A humming motor that will not spin overheats the windings into a short. Kill the breaker and call for a diagnostic before a $200 capacitor turns into a $1,500 pump replacement.
Call Adam's Pool and Spa Service for a motor diagnostic, an itemized quote, and a repair backed by post-repair service. We answer Monday through Saturday, 7 AM to 5 PM.
