• Disconnect the power switch wire harness and remove the power switch.
• Connect the power switch wire harness to the new power switch.
• Reinstall the power switch and secure it with its mounting screws.
• Plug the heater's power cord back into the wall outlet to restore electrical power.

What to do when your Suburban wall heater won't power up

• Check the house circuit for the heater to see if the house circuit breaker tripped. Reset the house circuit breaker to restore power to the heater if you found the house circuit breaker tripped.
• Check the thermostat temperature setting and adjust the thermostat setting if the thermostat is set too low to turn the heater on.
• Some heaters have a thermal overload switch that shuts off the heater if the heater draws too much electrical current due to a short circuit in wiring or a heater component. Reset the thermal overload and see if the heater works.
• If the thermal overload keeps tripping, unplug the heater and check for damaged wiring or a broken heating element.
