I need to replace this resistor.(r24) there are no colors on it. It is on a board inside a garage door opener. It runs the safety beam. Any help.. Thanks..

 

Make and model of unit?

 

That is a high wattage wire wound, you will have to measure the metal conductor each side of any break.
They are available but not exactly in that format, maybe
Max.

 

And you will need to find and replace whatever caused the resistor to release its smoke.

Miracle Industries Inc. Very old unit..

I hit the resistor and snaped it when replacing the light bulb...

 

The resistor was already cooked before you snapped it.
Can you post a photo of the back side of the circuit board?

 

Fortunately its not carbon so should be easy to measure with any oxide surface cleaned first.
Max.

Will do later tonight. At work.. thanks. It was working before i snaped it. Garage door was operating.

I am completely convinced it is wirewound. It could be a film resistor as they also have a spiral element.

I don't see a break in the spiral so probably one of the end cap connections to the spiral was opened. If so, you should be able to measure the full value from end to end with a little wiggle on the loose end.

I'm not sure what that string is there for but resistors of that type make poor accessory hangers.

Simple. The string is the TS' clever way of pointing to the component in question.

 

Any idea where I could buy one to get my garage door working?? Or real easy directions on how to measure said resistor? And then what to ask for when ordering.. Sorry to be a pain in the a%# but I know nothing about these part.

 

If you can't get the exact replacement type, I would attempt to measure it, most likely very low Ohms, and look for a 10watt wire wound at Digikey etc.
Max.

You need to buy or borrow a multimeter to measure the resistance. Places like Harbor Freight have very inexpensive ones. Make sure the power is disconnected then follow the meter instructions to set up the meter. There are tutorials online that show you how to measure the value of a resistor. In your particular case you'll have to wiggle the end caps of the resistor with the meter probes to get a reading. You're also going to need to be able to unsolder the old resistor and solder the replacement in. Let us know how the measurement goes.
