Main Oven temperature drops after it has reached temperature. Temperature Light comes on again once temp has been reached but temp continues to fall.

probably the element. to save wasting money, check continuity with a multimeter

Hi ya mate sorry to hear your having problems with you oven,

The problem wiht your oven seems to ba a faliure of the fsd/ffd, it seems to me that this device is not completey gone but is faulty.

This device is used as a safety feature on gas ovens and is there to turn the gas off to the oven when the flame has failed.

The way it works is that the intial small flame heats up the the phile at the end of the cappliary tube which is connected to a valave which realses the gas to the oven..


what you need is to have it change


hope this helps

cheers

You will need to replace the temp probe Call704-891-6557 we'll tell you how to do it safely.

Hi,
If your electric oven is not heating then you probably have a bad heating element in your oven. This is not that hard to fix yourself...
Check out this tip that I wrote about the Oven not heating problem..

hi remember that electric can kill you even if it is unplugged, if you don't know what components are likely to hold charge or have large inductance get someone else to fix it.

you need to get the service manual as tis will have fault finding charts, part numbers, location of sensors etc. If you can't get manual then:
Not likely to be temp limiter as this cuts out if temp is too hot. Find temp probe, may be ntc, mercury vapour switch etc. take probe out disconnect leads and measure resistance, heat, or cool, probe measure resistance if not significantly different (ie 10k to 100k or 100k to 300k) then probe is shot. Take probe to spares place, get replacement and refit. Be very careful to refit leads exactly as they came out, don't want insulation to melt and oven to become live. test with oven or meat thermometer as new sensor may need calibration. Should be accurate to within 10C or so

hope this helps
