MFF384KCF Frigidaire Range - Instructions

Called fridgidaire and they told me the a F31 code means my temperature sensor is not working.
So I ordered one online. I installed it and I still have F31 code and still won't work. So what now? Do I trust them to tell me another part?

Really a no brainer, but I do have to say that PartSelect customer service is excellent. My part was located and on it's way within a day and arrived a couple of days later.

I unplugged the Stove/Oven electrical cord from the wall, then removed the oven door by unlocking the door brackets with a flat head screw driver then closing the door to the last position before it closes and removing the door from the stove (found instructions on YouTube - very easy, which is optional), then removed the oven racks. Removing the door made it a lot easier to access the broil element and element support bracket screws using a socket wrench. I removed the screws from the rear cover on the back of the stove with a socket wrench to access and disconnect the broil element wires with my hand (pliers if needed). I removed the old broil element and inserted and reconnected the new broil element wires, then re-installed the rear cover. I tightened the broil element in place then re-installed the element support bracket and screws, replaced the oven racks, re-installed the oven door and plugged the stove into the wall. This took about twenty minutes and the broil element is working fine.

I followed two very good videos on how to do the repairs. It took longer to clean all the disassembled parts and the glass than it did to actually do the repair.
A word of caution: Be sure to lock the door hinges in the open position before you lift out the door. They must be locked open to put the door back on. It's difficult to lock them open once the door is removed. Also when you replace the screws get them all aligned in the holes before you lock everything down.
The infinite burner switch was pretty easy to replace but watch out for sheet metal cuts when you are removing the back of the stove. I recommend gloves. My stove has a 12 inch infinite burner, but the parts list only mentions a 10 inch burner. Before I ordered it, I had to call the company to verify that it could be used for the 12 inch burner as well.

If you do not intend to take apart the oven door to clean the interior glass, I would recommend you use a clamp to hold the handle and oven door tightly together while you replace the screw. There is a spacer between the back and front panels which could otherwise be shifted out of position. I used a screw extractor to remove the damaged screw and then installed the replacement. Wish all appliance repairs were this easy!

Ensured breaker was off. My range is hot wired. Removed all cables from old terminal block with nutdriver. Used phillips head screw driver to remove old terminal block from back of range. replaced old terminal block with new one. Re-attached accessory cables to small terminals first, then the main cables to the terminal block using where necessary long nose pliers. It is important to make note of which cables are attached to each terminal of the block, so make a sketch PRIOR to removal. Also be careful how the cables are attached to the block. You are using 10 gauge cable with thick insulation. It is important that when pushing the range back into position the cable does not put too much pressure on the block as it will break it. That's exactly what happened to this last one. It probably cracked under the strain of the pressure of the cable and finally current running through it weakened it to the point where it broke off from the block causing it to short and trip the breaker.

So simple....removed back panel, removed knob from front of range and removed 2 screws holding the knob in. Used needle nose pliers to pull wires off existing switch, placed wires in identical spots on new switch. Put switch post through front of range and put the 2 screws back in and the knob on. Finished and ready to go in less than 10 minutes. No more sparking....

I removed back cover and replaced the probe. The troubleshooting info indicated this is the problem 99% of the time. Guess what, it did not help! Further checks indicate that broil element may be out. Am going to resistance check and order if that is the problem.

unscrewed brace attached to element without any problem and secured the wire so that it would not fall behind liner. Connector was a bit hard to disconnect so asked my handyman to detach it - I was not familiar with this connection and did not want to break it - he did it w/o problems and attached the new bake element pronto. How easy can it get!

Replaced control units that were malfunctioning.

Disconnected power first. Removed 4 screws on the back of the range, pulled the knob off of the switch, removed 2 small screws on the switch(on the front , under the knob) pulled off the 4 wires with spade connections on the switch. Put wires on the new switch, put in 2 screws on new switch, pushed knob on switch, replaced back cover and tested the new switch. Works great. Took less than 10 mins.

Pulled the stove away from the wall, disconnected the power cable, removed the top part of the back where the switch was. In front there are two screws that are philip heads that hold the the switch in place. Be careful when replacing the wires. When you take one wire off, place it on the new switch in the the same position. The switch can be put back, but be careful of the angle, because it has four screw holes. Replace the switch, replace the back, plug the power cable in, and push the stove back to it's original position. Make sure there isn't anything on the burner when you test the switch.

Removed bottom drawer. Pulled Range out away from the wall. Unplugged Range. Removed 6 screws from top back cover. Removed top back cover to reveal the Infinite Switches behind the knobs. Pulled the knobs off of the Switches I wanted to change. Removed the 2 Phillips Head screws holding each switch. Pulled the wires off of the old Infinite Switch and put them on the new Infinite Switch. I was careful to put each wire on the correct terminal from old to new switch. I then reassembled the Range in reverse order. I changed both 8" Burner Infinite Switches. I was only having trouble with 1 switch. But, upon inspection. Both Switches had burn marks on the top left of the switch.

The video was a great help. I could have replaced the switch without watching it, but it gave me confidence that I was doing it right. Everything went just like he said it would. Burner seems to work better now and no more scary noises.

Took back cover off 2 screws held the switch then moved wires one at a time from old switch to the new one put everything back plugged in stove everything worked
