What does the red light on it indicate?
What does it mean when the red light is on? Does it require a battery replacement or anything? Or do I need to just replace the entire thing once that light turns on and it stops working?
Your heater is equipped with an
automatic reset limit control that will
automatically turn the heater OFF to
prevent overheating. Should this occur,
the red warning light will illuminate
and will continue to shine until the limit
resets. Your heater is also equipped
with a backup “one shot” thermal
protection fuse that will permanently
disable the unit, to prevent a fire, if the
reset limit fails. If the red warning light
illuminates and the heater never
restarts, the “one shot” thermal
protection fuse has been activated and
you should consult the factory. Please call us at 1-800-Grainger to speak with a Customer Service Agent and/or a Technical Product Support Specialist. Thank you for using Grainger.com Ask & Answer.
