There isn't one. If you had a brief power loss unplug it for 20 minutes and then plug it back in. It should restart. If this does not work.. Press the power cool and power freeze buttons for 8 seconds and then press the UP arrow to cycle through the menu. There will be horizontal and vertical dashes in the display if there are errors. NOTE the position of ANY dashes as they appear as there are actually 13 failure indicators via those various dashes. After the last menu the unit should restart. If it does not start after the menu wait 10 minutes to see if it restarts on it's own.
If you note dashes in the temp windows I need to know what window and what positon of the digital 8 indicator it was in. (upper, center, "top or bottom right and left sides" Top or bottom lines i.e exact digit as it would appear in a digital 8 display.
There are also things like the PTC relay, run capacitor or thermal overload that can cause this.
If you have no display at all.... your most likely looking at a control panel failure.
