who's an Electronic Engineer - need help

[EuroTall]

a capacitor or resistor or something on the circuit board from my home Air conditioner burnt up and the whole circuit board costs $600 ..... I know how to solder so if I can find this little thing and solder it on there it might do the trick and save me the headache..

can anyone identify the part for me so Radio Shack can help me order one or So I can find it on the internet somewhere'

thanks

It looks like a little lolipop with 2 wires sticking out .
Markings on it are

MCI
3D7141
2.5xP3

.................where x = the Omega symbol
(Omega symbol makes me think its a resistor of some sort but have no clue on that.....from what I can remember from my physics classes in college.)





TIA.

i took an electrical engineering class so i may be able to help out a little.

i'm not sure what that is... it doesnt exactly look like a resistor to me. resistors are cylindrical and have colored rings that tell u how much current it disapates.

BUT! the omega symbol stands for Ohms. Ohms are used to measure resistance so it very well may be a 2.5 ohm resistor.

no resistor disapates the exact amount it says so there is usually a +/- value which is stated by the color rings (which are not on there). maybe the "P3" simply stands for plus 3? which would also have to be minus 3. instead of having the rings since it's not a cylindrical shape they just wrote the value on it?

that's all i can make out of it.

thanks bro...i'm trying to find some material on these online but unsuccessful so far.
It's old...came off a fan blower control unit board made by GE for a variable speed A/C Handler unit in home....it's made in 1988 so a 16 year old part might be hard to find unless I can decode it and get an equivalent at Radio Shack or somewhere.

It is old, but there are plenty of the regular resistors on that same motherboard, with stripes like you describe. not sure why they would use this type of resistor instead of resistors known to me and you and everyone (the stripped ones),

Thought maybe it's some capacitor or Voristor or something, but can't decode it.

Thanks for you help

can anyone else take a stab at decoding this thing for me please?

could it maybe be a step-up resistor also and MCI (guessing they made it cause it says so) made it fool proof and got rid of the rings and just put the resistance value on it?

thanks Andre,you a good man.
appreciate
