need to check you fan wires, some have differant colors on the moter for the differant speeds, you may need to change the fan speed by unplugging one of the wires and replacing it with another. hopefully you still have the manuel , check with it first!!!

Sounds like it has a bad fan switch wich is no more than a small circular bi-metal switch that expands when heated closing a switch. Get a parts breakdown off the net. I am sure you could find the switch in your area and replace it yourself.

Its probably trying to tell you something is wrong with me.. find the root cause!(like the fan motor is stopping and then the heat builds up and tripps the high limit switch!

Just repaired one of these, problem was that main gas valve was not opening, valve is controlled by a vacuum switch, vacuum is created as fan blows air down tube past bent up metal flap near front bottom of heater (slight low pressure zone created). If vacuum switch is miss adjusted it will not close when fan is running and no gas flows. this is easy to check as vacuum switch also has a pressure port on it. With gas disconnected, remove bottom cover, locate vacuum switch (it has a hose clear plastic hose connected to it, in opposite corner is another hose connection, attach a length of hose to it that you can blow lightly into. With heater plugged in and no gas connected (USE CAUTION OF WIRE!!!), turn heater on you should hear after a few seconds the ignition and then a loud click as the gas valve opens, if no click blow lightly into end of your added tube, if you now hear a click the gas valve just opened. if you stop blowing you might hear the gas valve click again as it re-closes. If this is the case the vacuum switch needs to be adjusted slightly. THIS switch is hear for your safety, Adjust at your own risk!!! This can be done with a screw drive in the top, rotate screw slightly while checking if the fan alone causes enough vacuum to make the switch work. DO NOT over adjust. check safety operation before hooking up gas by placing a piece of cardboard or wood over the air intake and the exhaust to block airflow, if the air flow is blocked you should hear the gas valve drop out and reconnect as air flow is reestablished. Hope this helps
