Professional service guidance
Diagnose the heater fault before replacing parts. Service involving electrical power, gas combustion, or the pressurized water system should be performed by a qualified pool-heater professional following Pentair instructions and applicable codes. Disconnect power, shut off the gas supply when required, and relieve water pressure before opening the heater.
For a technician servicing only one known failure, an individual replacement component may be more appropriate. Kit 461100 is intended as a stocked service assortment for ongoing work.
