How do I bypass the tip over safety switch on my mr heater propane heater . I only use it for golfing in a golf acrt and no inside use.But it keep s going off when it s moved or bumped

This wil possibly be either an issue with the cup holder itself or the sprung mounting clips on the actual heater. Some cup holder slots are designed for larger 'Jumbo' cups so the hole is too big for the heater body to grip enough. Another reason could be the spring loaded "legs" on the heater base may be weak or faulty. All I can suggest is contact Mr Heater directly to see if they supply an adapter of some type.

Since there are safety issues involved here, I suggest asking MR Heater Directly. It does not sound like you are switching from Natural Gas to propane (LP), but if you are be sure to ask them if any valves or vents must be changed internally. The different mixtures of O2 to gas frequently require SOME change in the system other than just the hose and supply type.

Don’t, the device is there to prevent fires.

This is not going to work in your golf cart. This is propane based heater with a pilot light. It will go out if you drive because of the wind blowing on it. I also believe all Mr. Heaters have a tip hazard turn off. I know the two I have do. If you really want heat in your cart I would recommend an extra battery, an inverter and a porcelain electric heater. Could be made to work very nicely in your cart.

When the pilot lights continue holding the button down for a full minute and then release. It should stay lit then to allow you to turn it to the on position. If the pilot will not stay lit after holding it for the full minute, then the thermocouple will need to be replaced.
Hope this helps.

Check body to motor ground wire and battery to motor and body ground.

When you say heats up do you mean between the cold and hot in the middle which is normal operating range or are you over heating and the temp safety system is doing what it is designed to do and shutting your engine down so you don't damage your engine. Check you water pump, Thermostat and radiator before you try pulling or bypassing that switch or you could ruin your vehicle beyond repair.

look in back of the heater where the fuel nozzle goes. you will see a plate with a bunch of holes, the ignitor and the fan. also there is a little button with two wires on it. these wires connect to two spade terminals on the millivolt generator. its sensing bulb is near to the fuel nozzle. the other end with the gland nut goes into the main valve body. when the heater is on, the flame hits the millivolt generator and makes a very small DC voltage which goes through the little disk [an overload] then to the main valve solenoid. if the millivolt generator is good then there is a voltage at the main valve solenoid and it keeps the valve open. in your case it seems 1) the overload is open 2) the generator needs to be replaced. please go to desatech site and order a new generator.

defective venturi or cob webs in burner

If the pilot will not light get a q-tip and alcohol and remove the wire grill and be sure the cotton doesn't come off the end of the stick wet the cotton with the alcohol and twist it and push it down into the pilot tube 2 full inches. Let the alcohol soak for 30 seconds and while twisting pull the q-tip out. Try this until the pilot lights.
