I have a 3.5 year young Fridigaire FEF368GQA; the clock started acting up two weeks ago but still had cooktop and oven functions, now nothing works. When cooktop or oven control turned on, clock flashes and top element gets warm to the touch in 0.5 hr. but that's it. Clock timer the problem? Is this typical of 21st century Frigidaire products to only get a couple of years use before crapping out, especially a $600 stove? Thank You

Richard, sounds like you did all the pretests. You'll need a new display panel. When you work on it, be sure to cut the power.

is there voltage going to the erc (electronic range control)?

All of the items you mention that do work, are 120 volt items.
All the items that do NOT work are 220 volt items.
Sounds like you have a voltage problem, you will need to use a meter to check if you have 220 volts a/c to the outlet the stove plugs into. Take care when doing the following, you will be around live voltage and could get hurt. If you are uncomfortable working with a live circuit best to call someone in to do it for you. Check for 220v at the outlet for the stove (where the stove plugs into), if you have it there, go to where the cord attaches to the stove and check at that point. You should have either a 3 or 4 wire cord on the stove, On the rear of the stove there is a terminal block that the cord is fastened to. Between RED and BLACK you should have 220v, between RED and WHITE and BLACK and WHITE you should see 120v. Another thing to check is that the nuts holding the wires from the cord to the terminal block on the stove are turned down tight. A loose connection there will give you the same problem you have as well.

do you have both legs of the 220v? on the board see if you have 120v at L1 and L2. if you do then you have a bad board.

the pf=power failure

try unplugging unit for a few min then try again, but you may have a bad control
