| Post subject: | Heater fan |
Hello, This morning I thought I'd test out the Sierra heating. In doing so I noticed that the fan only works on high speed. Low and Medium do nothing. What causes this? And how do I fix it? |

When you say heater box you mean the fan box or the box the controls are in? |

on the side of the heater there is a little metal plate held in by 2 screws and has some wires plugged into it, unscrew it and pull it out for a look, you might find the bimetallic strip is dirty |
