We too purchase the Kenmore Power Miser 12 gas Water Heater, only to have all the same problems that I already see online...pilot light going out. We've replace the thermoculper and my husband was going to replace the thermostat, but after reading Marks' advise, we're going to try that first. I cannot believe with all these complaints that nothing can be done for the consumer' that have purchased these horrible units. Hopefully something will happen.
