So, I have an LA01N booster pump that is powered by a Century B668 motor. Both are not older than 3-4 years old (inherited this pool this past summer).
I knew the pump was needing to be rebuilt so I bought the replacement parts for a DIY rebuild. Then right before I started this project, the motor bearings went out. So, I bought the replacement bearings. Once I took the motor apart, I realized I needed a new motor (completely corroded.....no saving this guy).
Bought a new B668 motor and installed the pump and plumbed it up. Everything was swapped out with exactly the identical equipment. No upgrades and no issues on the build back.
However, when I start the pump/motor, I get a slight electrical burning smell, but nothing is overheating to the point of shutting off. After noticing this smell, I have only run the pump while I'm there watching it and maybe for 15 minutes and maybe a total of 4-5 times.
I thought maybe the windings needed to burn off that "new motor" coating? JK. But I did think maybe there was something that was needing to be burned off while it operated for the first time.
I called Century and they said to no burning smell should come from the motor, but to check the amps. So, checked the amps and it's pulling 7.5 but is rated to pull 6.5. Called Century back and they said that the impeller is under load and I should install a reducing valve on the outflow side to help reduce this.
Has anyone ever installed a valve to reduce the outflow of their booster pump?
Could the impeller be bad?
Any other ideas?
I attached a picture of my pool equipment setup.
