Why won't the temperature setting raise when i press up or warmer triangle button on my pool heater it sits at the lowest setting which is 65f?

Answer 1

If the temperature setting on your pool heater won't raise above 65°F when pressing the up or warmer button, it may indicate a malfunction or a safety lock feature engaged. Additionally, check if the heater is in a specific mode, such as "economy" or "freeze protection," which could limit the temperature settings. Inspect the user manual for troubleshooting steps or error codes, and consider resetting the heater or consulting a professional if the issue persists.
