Can i use 0.1ohm 1W resistor to replace the three burned resistor?

Original is 0.2ohm but i dont know W? Is te problem in 0.1ohm or 1W?...the quieter you become the more you are able to hear...Comment

Re: Dps-240fb
Can i connect 2 0.1 ohm resistor to get 0.2ohm?
I am from little town with one electronic shop and they dont have all i need for repair

Re: Dps-240fb
the new K3473 FET arrived. I am still searching for 0.2Ohm resistor. I thought connect 2x 0.1 Ohm but there is no space on PCB board....the quieter you become the more you are able to hear...Comment

Re: Dps-240fb
i will put all together, i will use 0.3ohm 2W resistor for testing, i ordered 3x 0.2ohm but i have to wait week or two. IS that OK?...the quieter you become the more you are able to hear...Comment

Re: Dps-240fb
I guess the 0.3 ohm will be fine. If anything, it will just trigger over-current sensing at less power than before.Muh-soggy-kneeComment

Friends, The source is burning IC901 (tny268pn) and R910 (10R). Exchanging components source is beeping. What are the probable causes?

OK. I got the rocker switch figured out thanks to the good advice on this forum.
Now I need to figure out the correct wire to go to the switch from the broiler element and from the oven element.
This is a Whirlpool RDE3340 electric range.
The common wire on the switch appears to have a high temperature insulating material. I am guessing that both the wire to the broiler and the wire to the oven elements also need relatively high temperature insulation. What do I need to look for? The broiler is rated at about 2400 watts.
Where may I find parts... -
Hi to all forum members,
Got this faulty 350 watt atx psu dirt cheap from a local online seller as i am keen to use it as a learning tool to repair faulty power supply.
The faulty part is quite obvious from the burn area near the 16pin KA7500 BD pwm. The fuse is still intact with good continuity.
Upon power on ac, there is 5vdc standby power on cathode of diode D14 and about 10vdc on cathode of diode D13.(This should be the aux power to generate the 12v and 5v rail.)
Initially i replace the two burned resistors near my marked red arrow to 200 ohm resistor... -
We have an Lenovo Yoga 710 15ISK that we use as a secondary laptop. To cut a long story short, around May 2023, while traveling, I connected the laptop into an electrical outlet that was already switched on. Something made a "pfft" sound and the laptop refused to turn on after that. After getting back home, I gave the the laptop for repair to an informal repair person. He replaced the adapter and an internal motherboard part, but after he returned it I noticed that the LCD did not look normal. Essentially, every alternate horizontal line on the screen had gone missing. The laptop was... -
I currently have a customer's vintage fan on the work bench to repair.
It uses an induction motor with 4 poles. One of the poles is open.
I couldn't find the break so i cut off the original wire.
I have measured the other poles and the resistance is about 28 ohms per pole and I measured the diameter of the wire with my digital calipers and it is 0.35mm in diameter.
I need to work out how much 0.35mm diameter enamelled copper wire i need to order for it to be 28 ohms. I have used this calculator and it says i need 160.35 metres.
The enamelled copper... -
I was Ollie today which is a close out / surplus outlet store I do not go in there to often because you find things that you should not be tempted by but that is a another story
I saw a small space heater that used a wire type of heater element which I been looking for a while but not really hard mind you but when I saw this I grabbed it I going to go back tomorrow and buy the last one that is like the one I bought today because I need the heater element and the ceramic insulators and more of heat element wire because this one has two different wattage settings one 1300 watts ( tap...
