Replace the button with a new one just remember which wire goes to which terminal. you will need a soldering iron and electronic solder to do this trick , also make sure you un plug the transformer. by any chance you got any n-scale trains you want to get rid of . If you do send me the info @ robert.e.kelsey.jr@gmail.com I'am a disabled veteran with little funds.

How do you open lionel transformer cw-80?


On the base of the transformer you will find 4 tamper proof screws that you will need to remove to open the case. A triangular blade screwdriver will be need to do this. Once removed the tamper proof screws can be replaced with self tapping screws.

Why does my Big Buddy Mr. Heater make a whistling or humming noise?


mr heater makes a whistling sound as gas escapes around the gasket of the ceramic heating elements, that is ,all around the outside edges of the ceramic heating elements.

You can find out exactly where the gas leak is , by pressing down on the outside edges of the ceramic elements with a big, long
slotted (flat bladed) screwdriver while mr heater is running and hot.

The screwdriver needs to be long enough so that you dont burn your hands [the longer & bigger the screwdriver, the better] & it does not hurt to wear heavy gloves too, because it gets very hot, very fast in front of mr heater.
The thicker the blade of the screwdriver is, the less chance of damaging the ceramic heating element because a thick bladed screwdriver will not concentrate all the pressure in just 1 tiny point.

You are not trying to crack the ceramic with a wood chisel.

Dont press down so hard that you break the ceramic heating element, start by pressing down gently and gradually increasing pressure until you notice a change in the whistle or sparks comming out of the heating element as loose carbon deposits
come out of the heating element and burn in the propaine flame.

When you press down on one edge ,the other opposite edge may come up slightly, resulting in loose carbon deposits escaping and burning as sparks.

also, you may not be pressing at the spot where the gas whistling is comming from and will need to move the screwdriver flat blade around the edges, here & there, to test for the effect of pressing down.

When you press down on the outside edge where the diamonds stop, while mr heater is whisteling, the whisteling will stop & mr heater will run quite. Sometimes, just pushing down with the screwdriver will stop the whisteling ,for a while,and maybe a good long while.

The big pain in the **** solution is to put a new gasket around the
ceramic heating elements, but there is no guarantee that the new gasket will not whistle.
Its a big ,nasty job, which I would rather not do--so I just push down with the screwdriver, to temporarly stop the whisteling, I guess it depends on how much the whisteling annoys you, as to if you want to go thru all the effort & expense of changing out the gaskets, without knowing if it will still whistle when you are done.

Im just a diy guy that has 3 big buddys I keep going for 4 yrs now.
I took one apart to look 4 the cause of the gas whistling, and then put it back together. Funny,it stopped whisteling & that was 3 yrs ago. I didnt put in any new parts.

It may help ,a lot ,to increase the pressure with which the Mr heater ceramic is pressed down against the gasket material.


This is accomplished by a heavy stainless steel wire that runs behind the ceramic heater element and goes through sheet metal
tabs on each side of the ceramic mounting frame.
You can bend the wire and the tabs,but only a little bit, and be very careful not to break the tabs because the tabs are not repairable, to increase the downwards pressure of the ceramic element against the gasket material. This may stop the gas whisteling--
its a try & see thing, a finicky adjustment, that sometimes works
& sometimes does not and sometimes, after a week or two, the ceramic might reseat itself against the gasket material and the whistling stop. Mine did stop whistling, but not until a couple of months after i did the job, due ,i think to reseating of the cermic against the gasket material. its try & see thing.


also ,a gas tank that has higher than average gas pressure may start gas whistling up but the whistling will stop after you have burned up the higher pressure of the propaine.

My cw-80 Lionel transformer has button issues when operating both traditional and tmcc loco. the horn and bell sounds are goofy. and on some of my traditionaltenders the sounds are still on when the...


The CW-80 is not suited for electronic sound systems. The output is non-sinusoidal. When electronic sounds are generated for some locos, the sound will be garbled. Use another power source. The Z1000 MTH power source or similar is recommended as are many other older Lionel standard power xfmrs. For the sound stay on problem with switch off, try putting a fixed load on the tracks ie: An accessory of some kind (lights etc). Usually a fixed electrical load will fix this problem. Overall, I would recommend changing out the power source and save yourself a lot of headache..

Can I use the cw-80 transformer on any Lionel train set from year 1948 to the preasant , thanks George


You should be able to. The Lionel transformers all put out AC power, not DC and many Marx and American Flyer transformers will work too. The real question is total amount of power being drawn and whether or not you have the wattage to match your engine and accessories. With the CW-80 though, it should put out plenty. I run my pre-war 1666E engine pulling a full compliment of metal cars with no problems using a CW-80.

No voltage on the red terminal to power up the track. open'd up unit looking for broken on loose connection but found none.


Check the primary and secondary windings with an Ohm meter to determine if the transformer is bad. You should get measurable resistance through both coils. Hope this helps
