To Next PageTo Next PageWhat to do if my Lochinvar EnergyRite ERN-202-A Water Heater has no burner operation?
If your Lochinvar Water Heater isn't burning, first, check the temperature setting on the main control board. Also, review the remote thermostat setting. If the pool heater is locked out due to a fault, check the display for the specific fault and refer to the fault descriptions for corrective actions.
Why does my Lochinvar Water Heater have no display?
If your Lochinvar Water Heater display is blank, it could be due to several reasons. First, check the external line switch, fuse, or breaker to ensure 120/240 VAC is supplied to the pool heater. Verify the ON/OFF switch is in the ON position and that there is 120 or 240 VAC through the switch. If there's no voltage through the switch, consider replacing it. A bad main control board could also be the cause, requiring replacement.
