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:

Lakewood 5500 Heater - Here is a picture of the rear side of the open heater thermostat with the two switches for 600 and 990W at the left. The 3oz metal piece is the weight that broke off from the thermostat assembly. It fell down and made a short between the case and the power switch. There is a visible burn mark where the short occurred.

I am convinced that if the heater ever falls over, the metal weight will break off and fall down and probably create a short against the case. It may disconnect the 120V power at the thermostat or cause a high enough current to kick out your breaker in the house.

The attachment of the 3oz metal weight to the back of the thermostat is not strong enough to survive when the heater falls over; it wil break off.

as have not seen a Lakewood heater I can only guess it is the igniter sparking . and would only be normal for a couple seconds when first turning it on

I would suggest getting rid of it, if it got that hot, the integrity of the metal is now in question. You dont know the reason why this happened and it could happen again. Some of the issues with these are due to poor engineering and manufacturing. IF you want to attempt to figure it out, you need to get a meter that reads resistance and check the heating element resistance and divide the voltage by that number to get the amperage, then you can look and see what the wire rating is for the ampacity and check to see if it is in specification.
