It depends on how many flashes you are getting from the light. A steady, continuously blinking light indicate normal operation. But other flashes indicate that something is wrong with your furnace. On the inside of your unit's front panel there should be a list of diagnostic codes along with an explanation of what each code means.

If you find that there is an error code indicating a problem with the furnace, it is a good idea to contact a heating contractor as soon as possible to take care of it. We get a lot of questions in the forum about furnaces that are flashing error codes -- If you'd like to have a contractor take a look at this, we can help you find one, here.
