Question about Lakewood 792/JR Utility Heater

Open circuit on electric heater

I have a Lakewood 792 A electric heater. The fan started slowing down and finally stopped. Now the unit will not turn on at all. I checked the over-heat link (in series with the heating element) and sure enough it is an open circuit. I hate to throw this great heater away because of a small burned our device like the over-heat link. Does anyone know if it is possible to replace these links? Where would I get one and how would I install it? I can see that the one in there now is connected to the element with a crimped connector. Could I use a regular crimp solderless connector to connect the new link into the circuit? Thanks in advance for your advice.

    Thanks Joe. I will be sure to replace the fan motor when I replace the link.

Well, it's a little late but since this is still up and people still read it apparently, here's a few more pointers on problems like this.

The part that blew is usually called a thermal fuse, and appliance parts stores usually insist on knowing the temperature that is printed on the side in order to get you a replacement.
They should also be able to sell you heat-resistant crimp-on connectors with which to install it.

Small motors usually slow down and stop because the bearings are plugged up with dust and crud. A drop or two of light oil might work but more likely you'll have to disassemble the motor. Don't use WD-40 unless you like your house full of that smell, and if you do chase it with some real oil because it evaporates out of the bearings and leaves them dry eventually. Be careful not to bend the fan blades. Clean the bearings and the shaft until a white piece of cloth doesn't show any dirt.

For those of you with heaters still running, an ounce of prevention: Take care of the motor as soon as you notice it running slow. The slower it runs the hotter the coils get and if they get hot enough the thermal fuse blows and you have to hassle with replacing it. Also, nichrome wire eventually fails by breaking, stretching, and/or sagging; and the hotter it gets the sooner it fails.

FUSEABLE LINKS ARE AVAILABLE AT ANY APPLIANCE STORE IN YOUR AREA MAKE SURE TO KNOW THE WATTAGE OF THE HEATER. SOME PART MANUFACTURES HAVE A "RESETABLE" LINK. TAKE THE HEATER WITH YOU TO THE APPLIANCE PARTS STORE. SORDERING IS BEST BUT RISKY BECAUSE OF THE HEAT. IF THE LEADS ARE LONG ENOUGH YOU CAN WRAP THE BODY OF THE FUSIBLE LINK WITH A WET TISSUE ... AND BE QUICK WITH THE SOLDERING.NEED I HAVE TO SAY TO DRY COMPLETELY? THE FAN IS SHOT THATS WHY THE LINK BLEW ... DID YOU REPLACE OR GET THE FAN RUNNING UP TO SPEED???

Lakewood Model 792/A My heater has stopped working. The light indicates that it is receiving power. I checked the tip switch to see if stuck open. OK Next step please? Jeff


Separate the case and trace out the wiring you are looking for an over heat limit switch. These are usually at the top of the case. You should also go over the element with a volt ohm meter make sure it is good, once you locate the thermal overload check it with the volt ohm meter it should read closed or dead short. If it reads open here is your culprit. It has been my observation that replacement parts can generally cost as much as replacing the entire heater. These I can pick up all day long for $19.00 at Home Depot the call them milk house heaters. Good luck with the repair.

Lakewood 792/JR heater running w/o heat


Hi Spybotics. I have the same problem and I traced mine down to a burned out over-heat fuse link. Check out my recent post. My guess is that you are having the same problem as me. It's not hard to tell - just take off the rear panel and test the link (looks like a small resistor in line with the element) with an ohm meter. Open circuit means burned out fuse link. DO NOT bypass the link, as an extreme fire hazard will exist without it.
