F5 error on convection oven

My problem is a brand new unit that stops a minute or so into any setting I have tried and shows F5. I can clear it and use microwave but would like to use convention too. As a matter of interest, F5 shows everytime we shut down and relocate too.

    This is a Dometic micro/convection in our newly purchased RV hence the comment about F5 showing everytime we shut down and relocate. The model is DOTRC17BC or DOTRC17SSC.

    No other code appears.

    Thanks

I would suspect the thermistor / temperature sensor is the culprit... as your Microwave is new I suggest you to contact LG technical Support and get it changed/repaired.. http://www.lge.com/us/general/contact-us.jsp

Hi there..... F5 is a common problem that happens to all oven brands... please give us the brand name and model number of the oven... that ll help us narrow down the solution.....and also let us know if there s any other code coming along with F5.....

get back to us with the details....

    I would suspect the thermistor / temperature sensor, here are the step by step procedure to check ur thermistor............



  • Unplug the oven.

  • DISCHARGE ALL HIGH VOLTAGE CAPACITORS.
    Procedure


  • Disconnect the leads from the thermistor and remove it from the oven.

  • Visually examine the component side of the thermistor for corrosion.
    See below
    .

  • Corroded thermistor leads will cause such symptoms as:



    • "The fan motor has a mind of its own. Sometimes it comes on all by
      itself for no reason."

    • The oven runs for two minutes then shuts off (if it runs for just
      one
      minute, then shuts off-check the damper motor)

    • The oven will not cook in the convection mode.

    • The temperature is lower or higher than preset.


  • Check the resistance of the thermistor as follows.



    1. Zero the ohmmeter on the R X 10,000 (or R X 10K) scale.

    2. Referring to the illustration, measure from the "COMMON" terminal to
      the "HIGH" terminal (meter polarity is not a factor). The thermistor resistance
      should reflect the ambient temperature as shown below:







    3. Room Temperature

      Approximate Resistance in Ohms




      68° F (20° C). To 86° F (30° C)

      322,000 to 165,000 respectively





  • Measuring from the "COMMON" terminal to the "LOW" terminal should produce
    the following readings:









    Room Temperature

    Approximate Resistance in Ohms




    68° F (20° C). To 86° F (30° C)

    68,000 to 35,000 respectively



  • Measuring from "LOW" to "HIGH" should read infinity.



  • if ur not experienced in doing this work .... please be safe..... its not advicable to play around with electricity....


    if the thermistor looks fine its time to contact dometic.....

    contact Dometic through this page

    More contact info is here.










    if i ve been of help.... kindly rate my service........


    good luck

My microwave/convection oven (a GE unit model JES1290SK) started beeping every few seconds and displaying F6 on the control panel. I unplugged it and waited several minutes and when plugged in it displays...


The technical sheets in my files do not list F6 on the error code chart for GE microwaves.

Generally, these are the error codes possible on GE microwaves:

F1 open thermal sensor (convection models)
F2 shorted thermal sensor (convection models)
F3 key panel shorted for more than 60 seconds
F4 open humidity sensor
F5 shorted humidity sensor

There should be a "mini-manual" (technical sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, & testing.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

My Sharp microwave convection oven (R-967M / R96STM) cuts out during convection pre-heating and cooking, It appears it stops heating after 1 min. If the START button is pressed again the oven starts...


Also the fact it is a convection oven could mean the oven temperature sensor is not picking up the oven temp. it is not telling the machine it is there by the board seeing its resistance, the unit will shut off as a safety feature. The oven sees temperature by reading the value of a temperature dependent resistor. As the temperature changes so does the value of the component ( oven temp sensor) that way the unit determines the temperature inside the unit. Sometimes those sensors will break since they are in the area with the heat and moisture, they get old and break.

What does error message F5 mean?


There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, & testing..

I'm not finding the one for for this model online.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

If it's a convection model, F5 would be a damper door sensing error, which is usually a bad switch.

More info on switches is here.

One of the damper-related components, either the switch or motor or the damper door may be binding.

The damper is a door inside that opens or closes depending on cooking mode. If the controller senses that the door is not in the right position, it will shut down the cook cycle.

If it's not a convection model, F5 is probably a sensor error.

On some models, "SENSOR ERROR" appears on the display when:
  • Using the sensor feature, the door was opened before steam could be detected. Do not open the door until stream is sensed and time is shown counting down on the display.
  • Steam was not detected in the maximum amount of time. Use Time Cook to heat for more time.
Here's some info from Samsung, which is the actual manufacturer of these ovens:

"Some models are equipped with a sensor that can automatically adjust the oven's heating time based on the amount of steam in the oven. If your microwave is displaying E1, E4, or E5, there may be an issue with the gas sensor. For an E1 error, press the Cancel button and check on the food.

"Other microwaves do not give specific error messages and just display "8888" on the LED. If you get this error message, your microwave needs service.

"If the message is either ERROR or E-6, it indicates a mechanical fault.

"For all error indications, including the SE or 5E error, try unplugging the microwave from the outlet for at least ten minutes and then plug it back in. If the error persists, the microwave may require service. Please use our ASC Locator to find your nearest Authorized Service Center."

Feel free to contact me directly if you need more help.

The display on my GE Advantium microwave oven shows "LOCKED". I tried holding the clear/off button but it won't clear. the microwave is unusable at this point


The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If that doesn't work, leave it unplugged for about 5 minutes.

If yours is an Advantium, one of these owner's manuals will help you set the clock if you need help:

If you still need help, note that FixYa's Web site is currently not notifying us Experts when replies to our Clarification Requests are posted, so please post a new help request, but be sure to include your full model number from the tag in or on the unit.

It won't shut off and the control console shows just green blocks


The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If that doesn't work, leave it unplugged for maybe an hour.

If you still have trouble, to allow us to help you effectively (at no charge), please post a NEW problem to FixYa, and please include your brand name and the full model number from the tag in or on the unit, and detailed your symptoms.

Sparks during convection heating? That may be a shorting convection heating element.

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, & testing.

Code F6, E0, "Communication Error"


Hi. this code represents a key pad or control board malfunction. you will have to make sure the key pad or control panel connectors are connected tightly and securely. If the wires and connectors are secure, the actual control board may be faulty and you will need to replace it at this point.

first, get your money back or get a replacement for no charge. now, unplug the oven for 15 minutes and try again. if no-go, then some device is faulty that only a tech can find
