I have a Hydrotek with a Beckett Burner and it has worked fine for about a year - but I rarely use it. The other day I needed heat and used it for the first time in about a month. It worked for about 10 minutes and just stopped heating. I assumed I was out of Diesel so didn't think much of it but today I realized I was not out of Diesel so it stopped working for some other reason. Since I rarely use it is it possible that the Diesel went bad even though it initially started working? The "ON" light does come on but no ignition. Also, the plastic back of the little enclosed computer "chip" behind the temperature dial broke off I noticed...could this be it?
