How to Troubleshoot & Replace Frigidaire AP3874704 / 316418735 Clock Timer

I tested the temp probe first and found resistance to be ok at 1088 ohms (spec is 1000 to 1100 ohms) so that pointed to the control board being faulty. The board was easy enough to replace and took about 15 minutes to do. Disconnect the plug or throw circuit breaker to off. Use gloves to guard against sharp metal edges. Remove all four control knobs by simply pulling on them. Then unscrew the four black plastic nuts holding the control panel assembly in place. Flip panel forward then disconnect the two flat cables at the top by releasing the connectors on the board by pulling up on both ends of the connector body to disengage the flex tape. Remove the four screws holding the board assy to the panel and set the panel aside. Using needle nose pliers carefully pull off each of the solderless terminals and reattach them to the new board one by one. Then disconnect the white bodied connectors by prying on the release clip with a small flat blade screwdriver and reattach these as well. Make sure the two black connectors for the flat cables are in the released position by pulling up on the ends of the connector bodies to open, then insert the cables and push down on the connectors to close. Reattach board to panel using the four screws turning only enough to snug them down. Replace panel assy being careful to line up the rubber seal along the top edge. Replace black plastic nuts finger tight then the knobs. Check temps by using an oven thermometer and calibrate if desired using the procedure described in the owner's manual. 

I called Appliance Parts Pros and told them the code. They told me what the problem was. I ordered the Clock/Timer and received it a few days later. It took less than ten minutes to repair it. This was the most trouble free repair experience I have ever had. I removed the 4 control knobs loosened 4 nuts and removed the panel. I replaced the Clock/Timer and reinstalled the panel and it is working like a charm. 

After research and prayer I ordered the parts I believe correct. The no hassle return option helped my confidence to move forward. The parts arrived when promised and I began to remove an old part and install the new one so that I hooked the electrical properly. It must have worked since it all became operational when the stove was plugged back in. Amazing! 

Googled my appliance model for parts and after looking at several sites, came across appliance pros website. Looked through parts of appliance and found 2 conttollers. That's when live help became my savior. Ordered part, overnight tome,watched online demo video, and 15 minutes later appliance was fixed.o 

I called an appliance repairman who told me the clock/time control unit was bad. He quoted me $500 for parts & labor to fix it. I asked if I could replace the part myself. He said sure. With the model # I ordered the part from Appliance Parts Pro. It cost $240. Replacing the control new unit took me about 15 minutes. Everything works great now. 

Looked on the internet to determine the F13 error message and ordered the part from Appliance Parts Pros, viewed the video on how to replace the clock/timer. Very simple repair for the do-it-yourselfer. 

Installed new Clock/timer. That fixed it!!! 

Used your web site read and talked to service tech. You guys are the best, thank you for help! 

Frigidaire range - Broiler didn't work. Checked element - about 20 ohms (OK). Problem was oven control unit. Access was difficult - slide-in range so controller was in front. Five wires, four connectors and two ribbon connectors. The ribbon connectors were a challenge - needed magnifying glass and good eyes. New controller fixed problem. 

Looked on line to find others with the same problem. Determined what to replace and contacted ApplianceParts and ordered part.
