Google IRFZ34N ?

I already provided this link:
IRFZ34N is the part number.

So the Mosfet replacement i only need to be concerned about the number IRFZ34N , the other numbers dont matter.. Also what is the round black thing called on the board.. it says fan voltage on the top of it..

The part number and package style are all you need. So you need this exact part IRFZ34NPBF. The "N" specifies a TO-220 package style and the"PBF" indicates that it is lead free.
The big black round thing is a capacitor. It is most likely part of the power supply and is used to filter the ripples from the rectified ac power to make it smooth dc power. If the stove is running the same on ac or battery, you don't need to be concerned with this.

ok thanks , the stove is running the same on AC or DC...

No. It's not the same part. That part will run much hotter in the circuit and will probably fail. You need the exact part number that I gave you.

The listings in the US on ebay are all high (>$9ea total cost)

If you have some aversion to going to an electronics parts distributor you can go here:

http://www.amazon.com/IRFZ34N-MOSFE...e=UTF8&qid=1392577966&sr=8-1&keywords=IRFZ34N

The price isn't any better though unless you have Amazon Prime. Then they cost $0.72 ea.

You're welcome.
Be conscientious about using your ground strap.
The best way to remove the old component is to cut the leads, leaving enough of a stump to grab with a tweezer or needle nose plier. Then unsolder the individual stumps. This does the least damage to the circuit board. You don't have to heat all three leads at once or put stress on the plated holes to wiggle the component free.
Good luck

I will use my ground strap , very good advice on removing it...should see these in about a week or so..

It would be nice if you had a SMD heat gun............
But If you wanted a length of solder wick and the correct solder, I would drop some in an envelope and send it out to ya. PM me address.
This will give you nice clean holes and pads.

 

[rick31797]

Appreciate the offer, this is what i have , its is 30 watt, , not sure what kind of solder is with it..do you think this will do a good enough job...

I am not sure how to PM here

The issue you had that started this thread with a new motor barely turning except on "clean"...I have a similar issue. Did you ever resolve yours and, if so, what was the resolution?

I was never able to fix this problem and the board was to much money to buy, and not really knowing 100 percent if the board had failed, So being the stove not worth fixing , i bought a new stove that i can go into my local hardware store and buy parts for it right off the shelf, thelin service sucks, and there prices for parts are double what they should be..My old thelin was stripped of parts and the parts sold, the money i got from parting it out, paid 1/2 the cost of the new stove..So it all worked out...

 

[GeHmTS]

Probably the same Thelin stove buyers incognito bought the parts and will now mark them up 136% and resell. Sorry to perpetuate the myth, but I couldn't help it. In the end, I'm glad it all worked out for you.

Well, I think I'm going to go forward with my repair attempt. As expensive as the parts are, the cost of another stove plus a UPS is prohibitive enough for me to trouble shoot this one. Thanks for the response!

Keep us posted.
