Hi there. Could I get some more info please? What kind of heater it is. Make and model please. thank you
Is there an error code that comes up when it isn't working?
is there a pattern to the flashing lights? 2 flashes? 3 ?
could be a number of things. Could be as easy as a loose electrical connection. If you can smack the heater and it runs better for a small length of time that tells me that there is a loose connection somewhere or the unit is dirty and needs to be serviced. I suggest going on the internet and typing in the make and model # ***** looking at the owners manual. Go to the troubleshooting pages an you might have a better understanding on what parts need to be cleaned and where
