790.7921 Range works,Broiler works,warming drawer works but bottom burner doesn't and read-out shows up to temp/ no error code.

Hello Friend, this is Z. I am happy to assist you!

I see that both the clock and burners of your Frigidaire range are working but your oven does not bake or broil. May I have your model number please? You can normally locate the serial tag (which provides your model number) in the storage drawer, on the right side. Also, think about what may have happened prior to this occurrence. For instance, did you notice any strange functions or any other error codes prior to this issue? With this information I can better address the issue at hand.

Meanwhile, let's try resetting your range by either unplugging it or flipping the household circuit breaker to the off position. It is important to wait approximately ten minutes and then turn your range on. If resetting the power does not correct the issue, could you please advise me if the issue continues or provides an error code. Thank you!

I don't know about the burner... but the oven needs a safety valve (or the igniter) The safety valve is about $140. some people would rather replace the whole range than pay for the part and the service call.

see this instructions and fix it. God bless you

Although gas range oven may prove useful for cooking and baking, they may fail to ignite if they aren't properly maintained and set up. Lighting a gas range often involves simply turning a knob; however, blockages from food particles and debris caught in the burners, improper burner cap installation and gas supply are common problems that interfere with your gas range oven's performance. A few troubleshooting guidelines may solve these problems safely.

     Check you have gas in your tank if your gas range oven won't heat. Contact your gas supplier if you've run out of gas.

     Clean the burners if you have gas but your burners still won't ignite. To clean the burners, lift the burner caps
   • 3
     Inspect the small vertical holes on the side of your burners for dirt, food and debris. The gas won't ignite if they are clogged. Scrape dirt, debris and food from the vertical holes using a pointy object such as a toothpick or paperclip.

     Reinstall the burner caps properly. If they are tilted or wobbly, the gas may not ignite. Install the caps on the right burners. Some burners are smaller than others, so match the caps to the appropriate burners.

     Move the burner knob to the "Lite" position and wait for the gas to ignite. If it ignites, rotate the knob to your desired setting. If it doesn't ignite, contact a qualified appliance technician.
     
     

Hello & Welcome to FixYa

This indicates an open/shorted oven temperature sensor and to solve this problem the sensor needs replacement. If you wan to be sure before replacing the sensor then you can test it with a voltmeter for around 1100ohms....if it reads more then this then it needs replacement however, if the reading is around or less then 1100ohms then it is the control board that needs replacement. Please get back to me if you have any other questions.

Hi,

Here is a tips that I wrote that will help to explain why you get the PF Error Code

Check resistance of lower burner ignitor. Should be above 4ohms. If not, replace. Part 40-75$ + labor. Let me know if info helps- ED

This is what I would do: I would unplug the range and connect my test cord to your range cord. I use an ammeter along with my test cord to read the amp draw of the bake ignitor. If it cannot get above 3.5 amps I know the ignitor is bad or weak. Since the oven is working that means there is a good circuit. In order for the safety bi-metal to open the amp draw must reach 3.5 amps or better. So to me I am thinking bad ignitor. To get to it I remove the door oven racks and bottom, I then remove the flame spreader and unplug the quick connect to the ignitor. I remove the burner and ignitor and replace the ignitor on a work bench. I am too old to be bending over and trying to do any parts replacement inside an oven. LOL. I have a training film which shows how the silicone carbide ignitor works HERE. Post a model number and I may have a service manual, do not forget to rate the answer.

Some gas ranges may take 10 or so minutes to light.
Other than that you may have a defective glow bar ignitor.
If it glows and does not light the reistance in the ignitior has failed.

Check both gas valve solonoids for 216 ohms [blue broiler wire to the orange common and red oven wire to orange common] both must be ok.

Check oven temp sensor for 1080 ohms.

If above are ok then the problem is either the spark module or the control board.

Since the gas valve was not opening and there was not ignitor sound I replaced the spark module for about $90. You have a 50-50 chance of being right.

My range is relitively new and I'm haveing an oven light problem which I traced to the control board so I may replaced this board to for about $200.
