However, the 2 little yellow lights come on so the electricity is reaching them.
The Lakewood 5500 heater may not heat, yet all lights are on, due to the thermal fuse inside the control box being blown.
It works like a normal fuse, yet will blow if the temperature gets too hot. When it opens, it will prevent any electricity to get to the heating coils and connot be reset. It must be replaced.
You can open the control area by removing the front foot of the unit, removing another screw behind that foot. This will allow you to slide the whole control end off the unit. At the bottom next to the heating element, you will notice 3 wires to the elements - red, blue, & white.
The white wire runs underneath the terminals & is sheathed. Under this sheath is the thermal fuse.
Be sure to replace it with the same temperature rating (167 C).
I don't recommend bypassing the thermal fuse, however, due to it's a safety issue.
I found the fuse at the following link:
