20 Most Recent Patton PUH9000-U Heater Questions & Answers

My Patton PUH682 utility heater from 2011 is otherwise in excellent condition but Auto Safety Shut-Off seems to be a design problem. My overheat sensor quickly shut off the unit when surrounding air was cool. It is inside the bottom of the fan box wired between the on/off potentiometer and heating coils.
I identified it by turning on the heater and watched the metal contacts separate as it tripped. On my unit, the defective overheat sensor is hardwired. Since it was otherwise useless as a heater, I decided to jerry-rig it and hope for the best. I pried back the sheet metal edge of the fan box and wrapped the sensor with electrical tape. Then I took a very small squeezable metal paper clip and lined it with electrical tape. I clamped it over the overheat sensor and it fits perfectly to prevent the metal plates from separating. Now the heater works the way it should. The cable, coils and plug don't overheat on Hot setting and it runs continuously.

MILKHOUSE HEATER "CAUTION LIGHT" SOLUTION: Before I explain, let me clear this myth up: this is NOT an issue with the pendulum safety switch (some mistake that for a "mercury" switch). To begin, unplug the heater. Open it up and clean it out. I mean, buy a can of non-chlorinated brake cleaner and squirt all of the contacts good. Below the fan there is a sensor mounted on the heater element box on the bottom. That goes bad and causes it to trip. While you are there, squirt the motor bushings good with the brake cleaner and dab a drop of synthetic motor oil (just a drop) on EACH of the two motor bushings. Personally, I rewired this and bypassed all of the safety features. You can bypass that sensor without soldering or cutting any wires. All you have to do is unscrew the wires from the holder and then unscrew the tiny nuts and tiny bolts. Then bolt the together at one end (note the position) and put it back in the holder and tighten the screw to hold it in. This method fixes the issue completely as it removes the sensor from the equation. In fact, I just did that on my third milkhouse heater and it has been running solid for the last 15 minutes. Use your modified heater with caution! Let the brake cleaner dry before you energize this device!

Here's a link to the site that has a phone number to call concerning the recall of last December.
Use it to determine if your model Patton heater was included in the recall.


There was also a recall in 1985.

If it is the same as mine it takes a minute or two to start after you plug it in...this is a safety thing,in case it tips over...if it is tilted to much it will shut off...but will sart back up in a few minutes...

if you blow a limit switch the fan continues to run in an attempt to cool it down,try unpluging it and letting it sit for about 30min to reset the limit switch,plug it back in if the fan continues to run with no heat replace the limit switch.

These fans have a safey feature (sensor) that shuts the heater off if it is tipped over. It sounds like this component is not functioning correctly - may be set wrong and will not allow the heater to turn on unless you shake it to reset the sensor. If it is still under warranty return heater, if not call Patton and ask for help.
