Replaced front high limit thermostat worked for a week and blew again. Checked all venting and there is no air flow issue. Could it be the rear thermostat making the front one blow?
ANSWER Hello Kim. You will need to check and see if the heater is over heating and causing the issues with the unit. If so, the cycling thermostat on the unit may need to be replaced.
