We had a power failure where the lights flickered off and on, and our stove displayed 'PF Sab'. I was able to clear that, and the burners work, but now the oven/broiler will not heat up. Is this something that could be fixed easily/inexpesively or will the repair costs equal getting a new stove?

Simple to test a bake element or range top burner element.
First, visually see if the element has molten gobs on the tubular-looking element, and/or is cracked. It will be obvious.
And if you do not see anything obvious, you should still test the element with a voltmeter. Many elements are set up so you can unscrew a screw where the element gets attached at the inside rear of the oven, and then pull the element into the stove a couple inches, enough to unhook the wires and then be able to put a voltmeter tester on each end of the element (set to the OHMS setting) to see if the element has continuity.
IF the element is good, then...
...You can also then make sure the wires are not contacting metal(BE SURE OF THIS),... and then plug the stove back in and test the wires to see if you have 220 volts. If not see, which of the two wires has 110. Then if you know which one does not have the 110, then you UNPLUG THE STOVE again and then access the rear of the stove and trace that dead wire from the element plug-in back in the range. You will physically be able to trace that wire.
When working with 220 elements in anything...please realize that usually one leg wire of the 220 volts (in other words, 110 volts) is always 'hot' even though the switch to it is off!! Always remember that!
The beeping sound is a warning because the oven is in lock condition. The oven is not faulty, and the code is not 5AB, but SAB.
SAB means that the oven is in Sabbath mode, and the control board will be locked for 72 hours with SAB on display.
If power is disconnected a new 72 hours cycle will start.
Push and hold the Clock button for about 10 seconds, that will reset SAB mode.
If that does not work leave the oven connected and off for 72 hours. If the oven does not unlock after three days, then the electronic control may be stuck in SAB mode because it is faulty, in that case contact the manufacturer at the number listed on the owners manual.
I finally found my manual to the range, and to change from celsius to fahrenheit press the BROIL button for 5 seconds. A tone will sound, and the temperature should switch to Fahrenheit.
As far as the code PF 5ab--it could be PF Sab which means the power went out during Sabbath mode. Try pressing and holding TIMER OFF for 5 seconds. If that doesn't work, then open the oven door, press STOP/CLEAR, press both the HOUR "up" and "down" arrow pad at the same time and hold for 5 seconds, "Sab OFF" should appear. Press START to accept the change, then close the oven door.
