Please give instructions for installing Probe Part# AP3969435 thanks Dickie
Answer Dickie, You'll need to: Remove power to the range, slide the range out of the cabinet opening. " Removing oven sensor: 1. Disconnect power and remove back panel. 2. Unplug wires to the sensor. 3. Remove the two screws holding the sensor to the back of the range."
Reverse the procedure and test the range oven for heat and error codes.
Greetings! My wife and I have noticed that our oven doesn't seem to heat consistently - sometimes it'll be a ~ 10 degrees cool, sometimes 15 degrees too hot. We're using a standard bimetal spring oven thermometer (which I know isn't the most accurate temperature measuring device). That being said, the things we bake don't seem to come out consistently done at the same time (cookies, cakes, etc.). What can I do to figure out what's wrong with our oven? Thanks!
Answer Joe, You want to get an accurate thermometer or multimeter with a probe and temperature setting TJMA-DMT3 place the thermometer or temp. probe in the cenetr of the oven cavity and pre heat the oven for at least 15 minutes. Allow the oven to cycle at least three cycles after the pre heat. make note of the temperaturwes, average the temperature readings after the three cycles , if the average hi temperature is within 225 dgrs. of the set temperature, your oven is working properly. If you wish, most controls can now be calbrated to within 5 dgrs. of the temp. setting, those instructions are usually in the owners manual.
Why can't I get part number AP3969435 disconnected? I have pulled and pulled but it won't come out.
Answer Hello Faye,
Many models actually have the harness secured with wire ties in the back of the unit. Sounds like you got one. This isn't the end of the world and you can fix it so if the failure ever occurs again you can complete the repair without having to remove the rear panel, but this time the unit will have to be pulled out and the rear cover panel will have to have the top 6 screws or so removed. This will allow you to droop the panel over while you are accessing the harness.
Be sure to unplug the unit so there can be a next time! Locate the temperature probe and follow the harness to the retaining apparatus. Remove only the harness for the probe from the retainer. As long as the wires don't contact metal, it will operate normally. This process allows you the slack required to access and change the probe from the front next time. Go ahead and change the probe with the unit out so you can observe the wiring after you're finished. The reason I want you to see it is if the connector is left between the panels where the insulation is, it will melt and cause a failure. Being aware of this and the physical configuration of the appliance enables you to better repair the unit in a long lasting manner.
Checked temp of upper and lower ovens set at 375 degrees. Fluctuated from over 425 to around 325. Seems to be a wide range - I expect some variation (+/- 25 degrees) but this (especially the 425+ is causing baking issues. What is the procedure for removing the probe for resistance testing? Do I have to remove the ovens from the wall to access the connections?
Answer Hello Dave,
The temperature of an oven is a deceiving thing when taking the temperature reading. You see, the temperature in the bake compartment is never constant since there is either a thermostat or an electronic circuit that turns the elements on and off. When taking the temperature, you must let it preheat first, then take the temperature with a digital thermometer over a period of three to four cycles. This is a time consuming process since you cannot open the door and must let the unit warm up to the highest point and cool down on its' own. This process has to be monitored so you can record the high temperatures and low temperatures. Once you finish, there will be 6 readings for three cycles or 8 readings for 4 cycles. When these numbers are totaled, you then divide by the number of readings you took. For example if you let the unit cycle 4 times, total the readings and divide by 8. This will give you the average temperature. The average temperature is the actual bake temperature used for baking recipes. The range can be astonishing, but this is how man overcomes the laws of nature.
If you want to read the resistance of the temperature sensor, you can do this at the control board or remove the sensor and test the resistance from the connector where it attaches to the harness. Sometimes you can get lucky and remove the sensor from inside the bake compartment and gently pull it out to get to the sensor connector. If it is done this way, you should be aware that if the connector isn't reinstalled so it is actually outside of the second layer of metal, it will melt and shut down on you again. The resistance should read 1050 to 1100 ohms at room temperature, (approximately 70°F).
Our oven runs very cool. in order to get an inside temp of 350 we have to set temp at 425 +/-. I was told to check the probe. At room temp it reads 1000 ohms. Is that close enough to the 1100 in prior question? we don't get any error codes. What else can I check?
Answer Hello Bob,
My knee jerk reaction to this is to check the breaker. If the element is only getting 120Vac instead of the full 240Vac as designed, it will take a very long time to never get up to the temperature it is set to. By checking the breaker I mean flip it off and back on and recheck the voltage. If the voltage to the unit is good, I would then go to the bake element and check from one terminal to the other. If you read zero volts or just a few volts, the element is good and the control is passing the voltage to the element. This would lead you to the sensor or the control. If you get 120Vac, discontinue power long enough to unplug one side of the element. This will isolate which leg of voltage you have lost. Follow the wire to the control and this is where you should check for voltage. If 120Vac is not there, you need to replace the control. If it is there, got to the other terminal of the element. If voltage is there, check the other side of the element where the wire is disconnected. If you lost it there, you have a bad element. I hope I haven't confused you. This can be a complicated procedure but disconnecting the one wire from the element will tell on the leg that has been dropped and you can trace it out from there. Just always use caution when near an appliance that has voltage on it and protective covers removed!
The oven heat runs out of control. 2 codes came up, F1 and F10. I purchased and replaced the probe. After I replaced the probe, I put the oven on bake and set the temperature to 200, the broil element comes on but not the bake element. The broil element does not shut down at temperature and continues to rise. What part should I replace next?
Answer Hi Lonnie. F1-F10 Runaway Temperature. (F10 only) Check RTD Sensor Probe & replace if necessary. If oven is overheating, disconnect power. If oven continues to overheat when the power is reapplied, replace EOC part # 316557200. Severe overheating may require the entire oven to be replaced should damage be extensive. I would use a volt/ohm meter part # TJMA-DM1 to assist. you in your diagnosis. Oven Sensor part # 316490001. Thank You.
Can you tell me what the resistance should be when checking part# ap3969435?
Answer Hello Jim. The probe 316490001 should read around 1100 ohms at room temperature and around 1650 ohms at 350°. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. Hope this helps. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
