    EA can be caused by a number of things. Check the flame sence electrode and make sure it's ok, condensate pipe could be frozen or blocked. Also there is what's called a bearing plate by the fan and they can stick. Remove the fan and feel up the pipe on the heatcell. If its intermittent it could also be a gas valve. While your at it chech the fan de-pressure remove the white nipple off the black plastic under the fan and put your manometer tube on it. It will give you a minus reading. Check the instructions as to what it should be, if it's under the heatcell may been cleaning.
