I have replaced my element on my Rangemaster Toledo Cooker

This answer was rated:

I have replaced my element on my Rangemaster Toledo Cooker but it still doesn't work. The light comes on and the fan goes round but there is no heat. I have checked with a meter and the there seems to be no problem with the wiring. Could it be the thermostat? The other oven and grill is working fine.

I have just checked and the light doesn't come on although the bulb is ok as I have tested it. There seems to be power going to the oven as the fan is working but nothing else.
Hello My name is Ian ~ I am not on the site constantly so please be patient whilst waiting for responses to you queries - could you let me have the model number please and I will have a look at the wiring diagram.
Customer: replied 2 years ago.
It says it is a Toledo 90 FSD DUAL FUEL ST. STEEL/CHR.
Customer: replied 2 years ago.
Thank you Ian
The model number is ***** located on a label in one of the draw spaces, on the back or in an oven door space. The information you have given me just refers to a range of 90cm dual fuel cookers with many variations.
Customer: replied 2 years ago.
Hi Ian, I have looked everywhere and I found a sticker near the bottom of the oven door but it says the same TOLEDO 90 FSD DUAL FUEL.
OK lets try and do it without, is it the main fan oven that is not heating?
Customer: replied 2 years ago.
Yes, The fan is spinning but no heat.
Customer: replied 2 years ago.
Hi Ian, I have called Rangemaster and the model is TOLS90DFFSS/
OK is the back still off and can you see the heater contacts?
Customer: replied 2 years ago.
Yes, They are a bit brown with heat but I have used a meter and there seems to be contact through the wires.
OK can you tell me which meter you are using and are you familiar with taking ac measurements?
Customer: replied 2 years ago.
Sorry Ian, I am not that clever. I have used a volts meter in the cont section and just checked there was a continuation of power going through.
OK if you let me have the name and model number of the meter I will talk you through it.
Customer: replied 2 years ago.
Sorry Ian. The meter has no model. Its just a cheap meter I bought years go. It has three sockets. One for Cont, one for 3 Volts and one for 5 Volts. Sorry I know it doesn't help.
Customer: replied 2 years ago.
It checks bulbs, fuses and appliances.
OK got you, well let me tell you how the thing works and then perhaps we can figure it out, power comes in, passes through a selector switch, then the timer, then a thermostat and then a thermal safety cut out which protects the oven from overheating and then to the element. First point of call is to check that the oven clock (timer) is set on manual (ie not timed or automatic) Come back to me when you have checked this.
Customer: replied 2 years ago.
I have checked to make sure the timer is not on. The other oven works fine. I have checked the bulb in the oven and that doesn't work either. So the only power the oven is getting is to the fan. The red light comes on when you turn the switch to operate the oven.
Customer: replied 2 years ago.
I have used the meter across the terminals at the rear of the switch and when you turn the switch it works ok.
Customer: replied 2 years ago.
Ian, where can I find the thermostat and the thermal safety cut out
Thermostat is connected to the thermostat knob at the front and you will need to take off the top cover to get at it, thermal safety cut out is either screwed to the cabinet side or on the top. What we need to establish is if you have power getting to the heater be in live or neutral. Once we have established this we can work out where the problem is. Hard to do without a multimeter.
Customer: replied 2 years ago.
Yes, I know what you mean. Would it help if I went and bought one?
Well you should be able to get one for about £15 which will do and be cheaper than an engineer and at least we will be sure of the voltages.
Customer: replied 2 years ago.
Ok Ian, Back in 30min
OK I am here until 1400 and then will be back at about 1700 if I miss you.
Customer: replied 2 years ago.
Hi Ian, I have the Di-Log DL9206 Multimeter. Hope this is ok.
OK black cable in common, red cable in v (right side) Select V next to off and you should have V ac in display if not press the blue button until you do.
Customer: replied 2 years ago.
ok done
Customer: replied 2 years ago.
It has auto at the top of display
switch on fan oven turn up the thermostat to maximum and measure the voltage across the two heater terminals/connectors that you replaced. keep your hands away from the metal probes and on the plastic - tell me what you get in the display?
Customer: replied 2 years ago.
Hi Ian its 0.428
now take one of the probes and put it on the case of the cooker and the other on first one side of the element and then the other side of the element and tell me what you get this time?
Customer: replied 2 years ago.
3.09 on the left and 3.08 on the right
OK can you advise if you put the probes in the mains block at the back that you actually get it registering around 240 volts
Customer: replied 2 years ago.
Is that where the main power comes in?
Yes
Customer: replied 2 years ago.
246
OK can you now keeping the probe on the positive connector (mains supply) place the other on one side of the element and tell me what you get?
Customer: replied 2 years ago.
245 on both terminals
OK that tells us that we have a break of supply on the positive side of the circuit. Can you give me an email address and I will send you a picture of an item I want you to check.
Customer: replied 2 years ago.
***@******.***
I have sent you an email of the thermal cut out, doesnt matter about the colour just a thing about the size of a pound coin and located somewhere near the fan assembly.
OK I have to head off for a couple of hours will come back to you on my return.
Customer: replied 2 years ago.
Ok thanks
Customer: replied 2 years ago.
Hi Ian, I have found it.
OK im back - set your multimeter to beep if you put the tips of the probes together you will get a tone if you have it on the correct setting when you're there come back to me
Customer: replied 2 years ago.
how do you get it to beep?
Four clicks right from off left of Cap. You may have to press the blue button to get it to work but when its working you will have a permanent tone whilst the probes are together stopping when you pull them apart.
Customer: replied 2 years ago.
ok at last. thanks
Customer: replied 2 years ago.
It has OL on the display
Right now pull off the two connectors that are plugged into the thermal cut out noting their positions. Once done put a probe on each tag one each side and tell me if you get a beep.
Customer: replied 2 years ago.
No beep Ian
Customer: replied 2 years ago.
I have taken the terminals off the other one and tested it and it beeped.
Is that what the problem is?
OK excellent - just to confirm, you see that you have one connector that is covered by a plastic sleeve and one that isn't - take the one that isnt and push it in the back of the sleeved one so that it is tight, then making sure that they are not anywhere near the cabinet switch on the oven and tell me if you now have heat, might take a couple of minutes. Then come back to me with the results.
Customer: replied 2 years ago.
Hi Ian. I have heat in the oven.
Excellent, well done, so you now have learned how to use a multimeter and can take voltage reading and do continuity checks in lesson one (laughs)
The part as we have discovered that is faulty is the thermal overload, its part number is ***** T093026 or just 093026 which you can get from your local supplier or using the following link on the internet -
