I have a Fisher & Paykel double wall oven that I purchased in 2005. The top oven which was used most often stopped heating up to temperature in normal time. What used to take 5 minutes to get up to 250 degrees now takes half an hour! What could be the problem? The bottom oven has had no issues and is working fine.

get an electrician in to fix it
the red wire is normally the active (power wire) and the blue is the neutral wire
if you fit the blue to a red terminal then you could be dead, blow the circuit or blow a circuit breaker
be safe call an electrician

as long as the block has all blue wires it doesnt matter

blue is normally your neutral wire and not live

Ours have also stopped working (both top and bottom). Bought in 2003 so only 8 yrs old. Getting technician in to fix. Will post solution. Also whenever oven is heated up the display panel fades and is not visible (has been doing this for a couple of years)

Hello & Welcome to FixYa

This indicates a 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.

You need to replace the temperature sensor in the top oven cavity. I can't get you a part number or price because I can't find any service info without exact model number. Contact your local appliance parts store. It is easily replaceable with just a coupla' hand tools.

Ovens Fisher&Paykel takes a long time to warm up.
What could the problem

Hi,

Seems like you found out the hard way what I wrote about in this tip...

Check it out it also contains some thing to try on how to unlock that oven..

hELLO THERE:
on these ovens the f-3 can sometime be incorporated with the f-4 error code also so here is the code and the things to look for both ok ?
F3 - F4 Open oven temperature sensor (circuit) (over 2700 ohms) or, shorted oven temperature sensor. Could be a result of:
· contamination on terminals
· pinched wire in oven temperature sensor circuit
· cold solder joint on control. · Disconnect power to range and remove oven temperature sensor connector from control.
· Measure oven temperature sensor resistance at oven temperature sensor connector (take care not to damage terminals in block) - Should read 1100 ohms at room temperature (approx 72 degrees F).
· Measure each oven temperature sensor lead from connector block to ground. If shorted, look for pinched or cut wire in oven temperature sensor circuit.
· Check connector terminals - Look for deformed or corrosion on terminals. Repair or replace.
If all above is ok replace control.

Is it the actual oven fan located on the back wall of the cavity behind the fan shroud or is it the cooling fan which is at the top of the cavity and blows air across the top of the oven? The cooling fan can't actually be seen.
