Lisa, you may have to contact the store where you bought it or contact GE. I looked all through the manual a couple time and nothing found on Demo mode. Check the attached links to contact GE for info., last link is USA. Good luck

if the machine has been put into 'Demo Mode' the cooling stops working. It is a special setting for when the unit is on the sales floor.... What is the model number and brand?
For Kitchen Aid the way to end DEMO is to hold the 'max cool' and 'cooling on/off' for several seconds until the control beeps...

Which model freezer do you have?

A few possible resets: press and hold the Set and + keys for 5+ seconds. On some models, that will get the freezer out of demo mode. On other models, it's the Set and Down arrow. For a few models, it's the Options and Up arrow. In all cases, it's press and hold both buttons until the unit responds.

I hope you will add a comment with the model of your freezer so that I can determine which set of instructions will work for your unit.

Hit options, scroll down to power, change to on. All done from the front panel.

Hello friend, that's a great question!
In order to put your Frigidaire refrigerator FGHB2866PF into demo mode you would need to push and hold the "up arrow" on your freezer and the "down arrow" on your refrigerator for five seconds. Once your appliance has went into demo mode both the refrigerator and freezer display should read 77. Hope this information helps. -Matt

It sounds like you have one of two issues there. Maybe you need to turn it off and wait for 10 minutes for it to reset (compressor has "vapor-locked" and the freon is not able to circulate through the compressor). The other option to try is that the refrigerator has entered into "demo" mode. This is the mode that it is usually put into in stores so that the compressor is not running, but all other things work for demonstration on a showroom floor. A voltage spike might have shocked it into the demo mode and will work in all ways except for a blinking light indicating the demo mode as well as no compressor activity to cool anything... Look in your operator manual to see if they mention the demo mode and how to enter and exit it.

Hope that helps.. I have seen both of these situations though.

If it is showing "OFF" then the unit is in demo mode. To remove this press the up or down arrow three times as fast as possible (within 2 seconds). This will start the compressor. I hope this helps.

You have done good work here young man. There is a relay or switch that is keeping the signal for being processed. I had the same similar problem with mine. At least your compressor is ok. Are you sure timer is wired back right.

the thermostat in the ice machine is not working. its most likely tha the icemaker is a FSP whirlpool it's a lot surer to just replace the hole head and be done with it unless you'd like keep dealing with it.
