Pool heater had kicked due to a thermal fuse blowing. After replacing the fuse I found that the heater was shooting flames out the bottom of the unit. I called several “pool” companies but none could come out for several days. I called Mowery based on their advertisement in the yellow pages and they were able to come out that afternoon. The repairman found several burners completely or partially blocked with spider webs, which ended up being the cause of the problem. The technician cleaned the burners and now it is working great!
