8 Trouble Shooting Guide
8.1 Symptoms and suspected causes are listed below.
Symptom #1
Stove/heater does not run when AC is present.
Suspected Causes:
• Stove control turned off.
• Thermostat setting below room temperature.
• Input ac cord to stove not connected to AC outlet of Surefire 512.
• Input cord of Surefire 512 not connected to AC outlet in wall.
• AC wall outlet dead.
• Stove defective.
• 5A fuse is blown.
• Surefire 512 defective.
Note: To ensure that the Surefire 512 is not the problem, perform the
following test:
Unplug the input AC cord of the stove / heater from the
Surefire 512 and plug it into a 120 VAC wall socket. This bypasses the Surefire
512. If the Stove / heater still does not work, then the Surefire 512 is not the
problem. Look elsewhere for the cause.
Symptom #2
Stove / heater works OK when AC is present but goes through repeated
on and off cycles when AC is removed.
Suspected Causes:
• Battery is low.
Fix:
Change battery or give the Surefire 512 time to recharge battery.
• Battery is defective.
Symptom #3
Stove / heater works OK when AC is present but shuts off when AC is
removed.
