SOURCE: I constantly got E1 Error code on my Kenmore Elite H3 GAS dryer

E1 error code indicates an open thermistor or open thermistor circuit. A thermistor is a component that relays the temperature in the dryer to the control board. If the thermistor has failed, Error code E1 will be displayed.
You need to call a repair person to fix it.

SOURCE: heater fires but only runs 2 minutes then shuts

the pump is not circulating, so the high limit is shutting it off. You need to check out your circulating pump

SOURCE: Stays lit for 25 minutes and shuts off

How large and sealed of an area are you using it in? I ask because those units have a low oxygen sensor which will shut it down if there is not enough oxygen in the space.(kinda prevents that pesky suffocation thing). Otherwise if using it in larger cold spaces, the issue is can be from the smaller tanks. As mentioned above, a larger tank can solve this, because these units have a fairly good input rate, which will cause the smaller tanks to freeze, and lower the propane temperature and evaporation rate, basically runs out of gas until the tank warms back up.

SOURCE: Have a Dayton Model 3e228D heater. Problem, unit

The fan switch on this unit is a bi-metal switch located on the heat exchanger. Check for a bad connection. It is 120 volts so be careful when checking. you can test the switch with an volt meter or one of those probe lights to see if the switch closes when hot. you are looking for 120 volts to the blower motor. Spin the blower motor to see if that is bound up with debris.

SOURCE: i have a master 150000 btu kerosene direct fire

The white smoke is the kerosene fuel hitting the hot combustion chamber. Your flame has went out. The cause for this could be many. The first thing you need to do is check your fuel. Remove your fuel cap and look at the bottom of the tank for trash or water. Use a good flash light. It will all settle to the bottom. If so, drain and clean out your tank. Add fresh kerosene. Check your fuel filter. Replace if dirty. Test again. If problem continues, It is possible that your photo eye could be deffective or just dirty. It is located next to the ignitor or spark plug. It sees the flame. If the flame goes out, the unit shuts down. The flame has to be smooth (not sputtering). Water in the fuel will make it sputter and the unit will shut down. When the water/moisture in tank settles to the bottom, your suction fuel line is just off the bottom which results in it picking up the water instead of good fuel. Always disgard the old fuel from previous year and start with fresh fuel. This will cut down alot of your problems in the future.

Fan on gas wall heater shuts off and on every 3 minutes, but the flame is on the entire time.


It always helps to add the model number of the item you want help on. However if it's like the newer units, the fan operates whenever the heater wall has reached a high enough temperature and shuts off when the heater cools off. It is not wired into your thermostat or electrically wired to the heater. It does that with a temperature driven fan switch in a little junction box mounted to the heater. Normally when that box gets hot because the heater is on the fan comes on, when it cools off the fan goes off. The junction box will have an ac cord coming out of it. If this fan switch junction box is not properly mounted it could be getting cooled off when the fan starts and then shuts itself off. After it heats up again it starts the fan. The other possibility is the temperature based fan switch is failing and needs replacement. See link.

Have a master 165,000 btu turbo heater it always starts and runs but sometimes it will run for 5 minutes 7 or 10 no matter where i set the built in thermostat,any tips ????


I would start by checking the fuel filter form the tank to the nozzle. If this is getting dirty the heater will slowly start loosing the red glow on the nose cone until the until shuts down.
Normally if it sets for a few minutes it will start and run again.

You can order a filter replacement kit that has all of your filters included.

Spa heater


You probally hear the fan at start up. If the heater won't fire the unit will shut down. This is probally an ignition problem or something in the safty circut. If you have your book on this it should have a trouble shooters guide. If your not comfortable with a box full of fire you may want to get a service person out.

Fire stoppes and fan still runs


1st take a air gun and blow in the fan to clear of debris. 2nd make sure to push your reset button on the back by your fan. Last you can calibrate your flame/heat by removing the fan housing & you will find 2 set screws try a small 1/16 turn on them and try to run, should run better for you.
