Where to buy vacuum solenoid switch that controls heat exchange?

Hello all,

Thanks to all TMF people who have helped me over the years with my white magic!

In the early fall my vaccumm solenoid switches stopped working and i have been using the TM ( albiet sparingly in the winter months-up here in Canada) by manually opening and securing the heat exchanger valves. This has allowed me to get hot water and i havent had any issues with overheating ( might be because of how cold its been?) But the water hasnt been as hot as i would like it to be.

I would like to order new solenoid switches. Can anyone recomend ones which will work with my tm?

can you provide some more detailed info...
Truckmount brand/model?
a pic of the solenoid?

If you are talking about the little blue MAC valves, it is rare that those go out. Most of the time they get clogged up with soap residue from overfilling the waste tank.

Hi Seagrtj,

Its a white magic commander ho... best pic i could get... had oil cap pop off/ spill a few months back and they stopped working a few months later. Had my tm guy look at it and test the system. We figure it must be these solenoids... sorry for the crappy pic.

Make sure those hoses are not cracked or damaged by the oil. I'd replace the vacuum lines first. Clean up that mess. Easier to solve problems when stuff is clean

Make sure your vac hose from the blower to solenoids AND from the solenoids to actuators are not cracked or loose.
