Is it okay to glue/solvent weld cpvc fittings to zurn-pex tubing?
Do you have sealed bearings on your new wheels? It sounds like it could be the gel or grease that bearings are packed in that is coming off in your hands. I know that Sonic makes a Citrus cleaner that is made for degreasing your bearings and it's under $10 a bottle. I hope this helps!
That could be your thermocoupler. It lights the fire for the heat. It should be on the right front of the dryer, sits right in front of a big metal tube. Costs about $30. Easy to change.
