My Kenmore Power Miser 12 gas WH won't reach the rated temperatures at the various settings on the thermostat. At "B" setting, the hot water is supposed to be 140F. It was actually 115F yesterday. At Very Hot, it hits 138F, not 160F. (I would never purposely set hot water temp at 160F. Only 140F or lower.). This problem has been building over time. I am talking about the temp of the water when I first turn on the tap after the heater has fully charged the tank and the burner is off. If I cannot get the proper temp, even when the tank is fully charged and the water has just been turned on, isn't this due to a gas control valve/thermostat problem? There's no mixing valve. Thyks.
