Funny, mine has TM504P150LS12 and I have double the components.
Found one datasheet but it is confusing, as it should be N-channel (by measurements), but datasheet states that it is P-channel

I remember when vacuum cleaners were simple. Good job on the repair mark.

Although the shipping costs were extremely high you still must have had a very good supplier being able to find the exact same mosfet Mark! Since even searching for a datasheet of this 7R540PL failed completely. The only ones I was able to find online were IRF540 mosfets and equivalents. But seeing the pcb tracks it possibly was a special dual mosfet like a IRF9952PBF?

Thanks Parasuraman,
It's important that we don't let our wives know otherwise we will be doing all the housework! That being said, it is good to do things together.
Glad you got my sense of humour.

Good Job!Mark,
If one wants to work in the technical repair field, he has to stock the relevant filed junk PCBs for replacement parts, As it is very difficult to get new parts and if the parts have to be obtained then the price is becomes very high due to logistics cost.

I also agree with Parasuraman Sir's comment about universally deportment wives....Ha Ha ha.....
