Nothing is more irritating than a heater that just isn’t blowing hot air. The heater could be blowing room temperature air, or maybe it doesn’t seem to be blowing air at all. We understand the frustration. After all, blowing hot air is the one thing it’s supposed to do right!
Along with your airflow woes, the heater may not be displaying any particular symptoms that could help you pinpoint the source of the problem. That just makes it harder to understand why it’s happening at all.
We can’t tell you what the problem is for sure without being there, so the least we can do is tell you about some of the most common issues.
