See section on power-saving mode.

Thats a rare model these days. Only one I know of is here

Did you wear static protection while you were working inside? That's not for YOU, it's for the electronics. They're wicked sensitive to static.

BUT... it might also be the case that you just didn't plug everything back in perfectly. Go back inside, wearing static protection, and doublecheck every connector inside. EVERY connector, even if it's on the other side of the board.

Turn off power. take off trim over door ( 2 screws). Remove 1 screw from top of keypad. Lift keypad up and out away from microwave. Use a Q-tip with 1 drop of alcohol to separate and clean between ribbon connectors. It is 1 ribbon that splits to 2 connectors. No need to unplug, Just gently clean between the 2 ribbons. They may seem glued together. When they are separated and clean put electrical tape between them. Reinstall keypad (1 screw). Reinstall top trim (2 screws). If it hasn't damaged the circuit board already it should work like new.

Hi

"Er Clean S" is a common error with Frigidaire which means shorted keypad. The issue is with the touchpad/keypad that should be replaced. However, before replacing the keypad you can unplug it and take it apart completely and use a hair dryer to blow some warm air on the keypad assembly to blow the moisture off. Hope this helps...please post back for further assistance.

The letter H appears in the screen. The register will not respond. Any idea to what the Letter H means?

FREE FIX!! Before you do anything else try this....

Blinking display with "ER S" on this model is a "keypad error" NOT a control board error. It occurrs when a button on the keypad is "stuck" for more than a minute most likely from being corroded - which can happen when the steam accumulates on the underside of the counter and drops down onto keypad (an apparent design flaw which frigidaire will do nothing about) - all the techs I've talked to recommend replaceing the entire plastic keypad assembly (oem part cost $125 at my local store). But they sell just the switch that is glued into the assembly for 16$ at www.repairclinic.com and it is a thin plastic film with electronic circuits running through it. Before you buy it though, turn power off at breaker, then try gently prying the keypad switch cover (the strip with the buttons on it) off of the top of the door panel (It is stuck down with a double sided clear tacky strip - I did it with a thin butter knife) and cleaning off any corrosion on underside of strip and on switch. Gently replace the keypad cover strip and press down around the edges gently. Then turning power back on to machine and see if that fixes it - worked for me - FREE!!! Worth trying before you call out a tech

You need the PC Link software for your model.
