Sta rite heater

Spoke to John in Parts, and he mentioned I should look into getting a control unit which is used to adjust temperature of water. Pool/ spa button is not working as pool water temperature is probably above set temperature. I can’t adjust temperature control to set temperature to 82 or 83. Right now temperature is set at 78 and pool water is at 78. Can you advise me if unit is worth repairing or new control unit is necessary. What is cost of new control unit?

John said that control unit is easy to install.

FYI I purchased Dynapro pool pump from Aquatech and installed pump and rejigged PVC piping.

Also heater makes whining noise after extensive heating 4-5 hours. If I take heater cover off whining gets reduced. Gas meter and piping from regulator has already been reduced. Pool heater is 8 years old.

Any suggestions?

    Stan you could have a bad membrane pad and or control board. Both kits come with install instructions. Price and availability can be found on our website. Click on parts and accessories and then click on the big yellow button Get pricing and Availability. IF the heater is making a whistling sound it sometimes is a result of inadequate gas pressure so do diligence and have Hydro check out your meter that it is sufficient capacity for your natural gas draw of your home. If that checks out you could have a bad combustion blower assy. Part can also be found on our website
    If all else fails contact our Service Support Desk to book a diagnostic and repair of your Maxetherm heater.
