I’m assuming that the reason my tumble drier doesn’t heat is becasue the thermal cutout has ‘passed-away’.
I have rotary motion but no warmth – any tips/suggestions on how to diagnose this problem?
Many thanks JMYou need thermostat kit number 1701557, available in the shop. Click on Shop@ to go there.
Make sure filter, door channel and condenser baffles are all clear and tell the Mrs not to open the door halfway through to see how the load is doing.
Pull the plug before fitting the stats…….
Regards,

Thanks Penguin.
I’ve already opened the rear of the machine and using a tester, I checked thermostats and heater continuity and found no open circuit. This indicated to me that the ‘thermostat kit’ is working fine; is this correct?
I’ve cleaned throughout and although drum rotates, the heater doesn’t seem to function. I’m at a loss now and assume that the problem is with the controller. What should I check next?

I should ‘double check’ the left hand T/stat again as I too am certain that is the fault 😕
I am assuming the water reservior empty and you have drained off any excess water in the Float Chamber as that will cut off the supply to the heater if flooded? It is rare for the Element to be at fault!

Re: Creda Condensair Model 37754 Doesn’t heat
Martin,
When I checked – I obtained continuity across each thermostat, which to my lame understanding, tells me that the thermostat is working. Presumably, at the operating temperature of each thermostat, the circuit becomes open until the system cools back down again.
I also checked continuity from one end of the heater element to the other and also continuity here – so the integrity of the element is sound.
I therefore conclude that the problem must exist elsewhere. Can anyone advise confirm my diagnosis and how I might go about investigating further?
Your assistance has been valuable. JM

I think there’s an exhaust thermostat on this model. Would have to get the diagram to be sure but one of the other lads will probably know.

You didn’t confirm my earlier assumption John, a possible answer to your question perhaps?

Worth a check I reckon 😉 Also the Front Thermostat in the Door Surround another possible 🙂

John,
You have split the circuit before metering the stats?
Left hand stat will read 30-45ohms if it has tripped, as you are reading back through the heating element.Regards,

From the outset, the water reservoir has been emptied. You mention the float chamber – where is this and how may this be accessed and checked?
Also, I wasn’t aware that there was a front T/Stat. Where in the door surround is this and how may this be accessed?

John,
We’re not allowed to specifically tell you how to strip the appliance down all we are allowed to do is give broad advice on the problems and help you along the way. If you have to ask those specific questions I’d strongly suggest that you get one of the guys in to look at the machine for you.
It’s as more for your safety than anything else.

John,
To ensure the float chamber is clear you simply remove the ‘user friendly’ drain plug at the back. If no water comes out, then it’s clear and should be fine 😉
The Thermostat is located on the plastic ‘drum’ surround at the front. (Sorry I typed ‘door’ earlier, but meant drum).
Pull the plug first before removing the retaining screws 😉

Martin,
Thanks. I checked the Stats again (including the door t/Stat).
With the spade connectors dis-connected, I have continuity across all Stats EXCEPT for the Rear LHS Stat; so I guess you are right.
Please confirm my rationale that this indicates that the Thermostat is mal-functioning. Replacement is obviously a straight-forward process.
Many thanks,
John M
Re: Creda Condensair Model 37754 Doesn’t heat
Hi
Can anyone help with my Creda Condensair model 37754 which doesn’t heat up?
It has the same symptoms as previous discussions although all 3 thermal cut out switches appear OK. The switches when out of circuit are all measuring 0 ohms i.e. closed. Sometimes when you switch the dryer on the heater element will function and then go cold some minutes later, whereas other times the element doesn’t function at all. I have noticed some wires which connect to a small black box (possibly some switch or sensor) next to the motor and timer rev which routes the supply to the element. What does this box do and could it be a contender. I measured the live connection to this black box and it read 180Vac.Scott
