SOURCE: Need a thermal cutoff for our Lakewood 5500

We have these heaters and haven't had a fuse fail yet. I think it's because after the first time I got that crackling sound after moving it while it was on, I stopped doing that, and only move it with the power off, and wait two minutes before restarting it, so the oil can resettle.

However, the thermostats are now failing. Anyone know if this part is available?

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.

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.

On the top of the switch (inside the heater) there is a common connection.....even though it looks as if it is connected (electrically), it isn't electrically affected by the switch; it's just used as a post. It's just the place where the striped wire connects to the "common" point for the heater coils (they are in a parallel). Also, while you're in there you might want to put some electrical grease on the exposed conductors.....mine had quite a bit of corrosion (which was the reason for the failure). I had to replace 3 of the female connectors.

sounds like a broken element or wire. with unit unplugged, using an ohm meter check all connections and check elements for resistance.

Find tip-over switch on Lakewood Heater


lakewood makes several styles of heaters,if it is the steam looking version,i don't think it has a tip over switch,because it cant start a fire...the tip over switch version has the counter balance switch in the casing under the coil and fan area..to check to see if it is working ,just turn it on and tip it over ,try it a couple of directions,if it shuts off it works.its not a thermocouple...

Got a lakewood heater jr 762 and the switch is burned out. Where do I got to find the replacement, or what's the part number? Thanks


I would assume you are talking about the thermostat switch. These switches are very simple to repair on your own. They are open without any housings and can be accesses by generally removing the panel from the heater. These thermostats fail at the two contact points due to the consistent arcing from opening and closing or on and off. These arcs create carbon buildup which then will not allow them to make the continuity necessary to turn the heater on. In some cases they may even fuse together keeping the heat source consistently running. If the heat source is continuously running with a faulty thermostat the thermal fuse may fault out. If the thermal fuse faults the fan may work but the heat source will not. These fuses will need replaced by an experienced person, you can generally pick these up on ebay for a few dollars. For carbon build up use a small wire brush to remove, while using fine sandpaper to drag between the contact points of the thermostat. Good luck. Mike

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.

I need a thermastat


If it's for the milkhouse style heater you show in this picture then go by a new heater, they are very cheap and the thermostat would certainly cost more then it's worth. I bought a heater like the one in the picture for around $13.00 at ACO Hardware wirth low, med, high wattage settings and with thermostat of course. A thermostat would likely cost at least $10.00 plus shipping so what would you do?

Hello, I have a Lakewood space heater, Model # 792/JR, and one of my kids tried to dry her shirt by placing it over the heater and now it comes on but doesnt heat up. Can this be fixed?


The heater "over-heated". It's supposed to have a safety cut-out. The question is, can it reset itself? If there is no manual reset button on it, leave it unplugged for 30 minutes or so. If it still doesn't work, spend $20 on a new one.
