Will the fan on the reddy heater not run if the ignighter is bad? When i plug it in the fan doesn't run.Do i need to replace the motor?


The fan motor runs regardless of the igniter as it is also the fuel pump. Possibly you may need to replace the motor but try this first. Remove the top section of the heater this exposes the fan motor, try spinning the motor by hand,it should spin freely if it does not try some light oil in the front and rear bearings of the motor and turn it by hand until it frees up. You may need to do this several times!! Now that it is spinning free put the heater back together and try it out. If it does not work a new motor is in your future. Hope this works out for you.

My reddy heater 115 pro starts, but shuts off after about 5 seconds of running , i replaced the filters and nozzle about 2 years ago


Here is a service manual:

http://www.desaparts.com/service_manuals.html

If the flames actually starts but the unit shuts off after 5 seconds you need to check the pump cover on your heater to make sure you have no cracks in the rear cover.
This could be from low pump pressure but most often this problem is caused from a defective control board.

Bearing have gone bad in the electric motor. You will have to replace the electric motor. They are expensive but still cheaper than buying a whole new heater.

Kersone reddy heater won't start, just buzzes


The R150B uses motor #097308-06, has a split phase motor. The secondary windings, which give the armature a jump-start, have gone bad. The motor is not serviceable. Try reddyparts.com - they seem to have the most parts.

Reddy heater 115 just turns on then shuts off


a new flame sensor is in order, if you have spark and it blows fuel then thats the answer. you can get one thet will fit from Mr. Heater for 3 bucks. the wires are different so just splice the to your old wire harness, there is no wrong way to hook them up.

try this, take off the top cover. plug in the heater and when the humming starts, rotate the fan sharply with a screwdriver. keep your fingers away from the fan. if the fan spins under power your start winding is shot. get a new motor. www dot desatech dot com
