Product review (5 stars): Fixed my dryer's flakiness
My dryer would not fully dry the loads.  Upon taking off the front panel and watching the burner, I could see that it fires up for a few seconds, then extinguishes.  When I poked stuff around, I found that one of these solenoids was intermittent.  A little pressure and everything works.

These only come in pairs, so I replaced both.  Why not, I'm in there anyhoo.
