Lakewood 792/JR Utility Heater Questions & Answers
Got a lakewood heater jr
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 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.

My heater
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.
My heater isn't working so i took it all apart and
Look this tells me that you should not be a heater repair person for one. Honestly these heaters are called milk house heaters and can be purchased all day long at Home Depot for 19 dollars, please purchase you a new one. Do not attempt any more repairs please, for your own health buy a new one!!
DOESNT RUN?
Between the poor fan motors and over heat sensors these are a throw away at $19.00 a pop. It costs more to repair than to replace it. But if you want to check it over here is what you do, separate the two halves, trace wiring from the plug to the switch thru the over heat sensor. You can remove this sensor only I would never run it unattended any more. Then a light oil on the fan motor bearings make sure it spins free, now inspect the heating element for breaks. Please limit how much you touch the element this can cause it to burn out quicker due to oils from skin and handling it. You will see that these are a very simple heater, cheaply made, but they do work well when they work. Now put it back together and see what happens.
