Turn of at mains, wait 5 mins and turn back on then consult your handbook to set clock. i suspect you have the oven on automatic by mistake. if this don't work, you may have a problem with the clock itself. you can bypass the clock by connecting together the two contacts adjacent to the clock relay

Simpson Harmony Nova electric oven heating problems (oven heats but no fan and light)

The Fan has ,in most cases, two functions - to maintain the oven temp and to clear any condensate or smoke coming from items being cooked. If your oven is over heating it could be the thermostat sensor faulty and giving a faulty reading to the fan. If you set you oven at 350F then sensors control the heat by kicking the heating elements off and in some models and makes the fan aids cool down. Make sure it is at a temperature that would trigger the fan to cool it down. It mostly relies on the regulation of the heating elements to control the temp. Only if it were to get hotter than the elements kicking off can control should the fan kick on. Not being at the site and actually seeing the stove it is hard to determine but if the fan is working every where else it should work when the oven is heating. Again check and see if there is a seperate sensor that monitors the temp of the over and triggers the fan. Not much help but that's where I would look first. Hope this was of some help.

Lower oven loss of power

I'd check the control switch first, and the wireing and connections.

I have just replaced the fan for this oven as it had stopped spinning. However it appears not to be the fan that has broken as the new one behaves the same. One important obserbvation is that when you...

Strange one this. According to the wiring and circuit diagrams, the yellow wire from the fan should go to contact 4 on the main oven switch. The oven element is connected to the thermostat, which in turn is connected to contact 3 on the oven switch. When the oven is on the handbook says that contacts 1,3 and 4 are made, contact 1 being the oven lights. So if the lights come on and the fan turns, the switch is more or less working. The only other thing that overrides the oven element is the thermal cutout. If you still have the problem, let me know what the thermostat neon is doing in all of this. It will be interesting to see what this is doing. Also, if you want the handbook which includes the diagrams, post your email address and I will send you a pdf copy.

My Electrolux EOB5610 fan oven will not heat up. The power light is on. The oven light is on. The fan works. There is some heat in the oven but not enough to cook with.

Only two possible causes. The oven element is faulty or the oven thermostat controller is faulty. Probably the first thing to do is test the oven element and check the resistance. If the element is okay then the oven thermostat will need replacing.

My oven turns off on me after only a minute never heating up fully

Could be caused by either of following;

1. Faulty thermostat.
2. Faulty thermal cut out switch. (controls power to cooling fan).
3. Faulty cooling fan (not fan inside oven).

Test thermostat by setting thermostat to low temperature like 60 oC. If oven gets much hotter then its a faulty thermostat.
To test cooling fan and thermal switch take oven out and remove top or rear panels to expose components.
When oven gets hot the cooling fan should turn on. If it doesn't then check to see if there is a mains voltage present.
If mains current exist but fan is not turning then replace fan. If mains voltage is not present then its the thermal switch.

Elan 948 OVen doesn't heat and light designating heating does not go on.

we just had the same problem with the same oven. pull the oven out of the wall. on the top right side there is a fan. there is a safety switch that is activated by the fan blowing on it. a piece of insulation was preventing the switch from activating so the oven thought the fan was not running. remove the insulation and the oven comes back to life.
