Do you know if the condenser cooling fan circuit has a relay and if it does, where it is located on the unit?

Thanks Honj. The price in AUS for a cooling fan is @ 550AUD so, if that is the fault the economics don't stack up. I will check for any issues with relays etc then take it from there.

Also, with the cooling fan removed I revisited the service mode. This time, I selected cool air mode (mainly just to see if anything would happen) it ran for a short period then stopped the Drying and Cool air LEDS were flashing (don't know if that has any significance)

Now, I am curious as to why the timer cool air mode immediately trips the RCD. After determining the heater element was not the cause and that it was more likely the cooling fan attempting to come on line after 80 secs into the drying cycle. In timer "cool air mode" when the RCD tripped it...

I managed to disconnect the cooling fan. Doing this also disabled the service mode, I could initiate it (Short+ Start) but pressing the start button selecting after the specific test mode was a no go. What I then did was to run the dryer in normal mode, the drum rotated & the air heated & it did...

Not yet Honj, I will keep you updated with my endeavour. What you raise, is an Interesting aspect of consumer law. There was a case in AUS a few years ago where the farmers challenged John Deere to service/repair their machinery. In the end, JD had to hand to provide the farmers (the owners of...

Where I wrote, is that logical ? I was referring to the cooling fan starting after 80 seconds (under normal conditions) into the drying cycle. That service mode is invaluable in fault finding (thanks Honj). I hope the cooling fan is OK & the fault is a something like a relay. I have several...

I have been thinking about why the RCD would trip @ 80 secs into the drying cycle and I think the reason is because the cooling fan is programmed to start at that point (either by time or temp) to start blowing cool air across the condenser collector plates. It didn’t trip on the heating test...

Thanks Harry, I’ve quickly looked at the area in question and I will try that next. I presume if the RCD doesn’t trip it is highly likely to be the motor. If it does trip, there is a fault in the circuit (relay?).

Thanks Honj, I appreciate your help. It is a really clean machine so I am hoping it might be a relay but if it is the fan then I am afraid it will be off to the recycling.

Thank-you again Honj. I went through the test sequences several times. I could feel the heat through the condenser door so very confident the heater bank is OK (which when I removed & visually inspected it, the part looked AOK) When I ran the cooling fan test (two times) the RCD tripped...

Thanks very much Honj for putting all this together. This machine is in the land of “Downunder” (the controls are at the bottom of the machine ). I tried the initiation sequence several times but unfortunately it didn’t generate a flashing START LED. I recall seeing somewhere about holding the...

Mod T494C Nr. 10 / 31829200

I see references to “service mode” , is this similar to “Built In Test Equipment” that can generate BITE Codes or something different?

Thanks Harry, if it didn’t trip on timer cool mode. I would get the heating element Meggar tested.

Thanks Harry, if it didn’t trip on timer cool mode, I would have the heating element Meggar tested.

Hi Honj, it is a Miele T494C

Thanks Harry, I do understand the basic principle of the RCD function (comparison of outflow vs inflow). What I didn't entirely understand was the term "insulation" but now I think the penny has dropped. I was thinking this "insulation" was a technical term to do with the metallurgy of the...

Thanks Harry. I have a rudimentary understanding of resistance however, I surmise my measurement of the cold wire coil only confirms it is not broken, where as the relevant resistance is when the coil is supplied with higher voltage . I presume if the resistance breaks down under this voltage...
