Please Help. I have an older model Coleman-Propane heater in my mobil home. I can hear the blower switch click, but it does not come on. I tried turning up the t-stat, it clicks, and still no results from the blower. Any more suggestions, before calling repair guy?

I'm not familiar with mobile home furnaces, but I have to assume they are similiar to home furnaces. There should be a fan control on this unit that controls the on / off of the fan itself. This is basically a temperature control that turns the fan on when the furnace has warmed up and turns it off when the furnace has cooled down. You noted in you post that when you turn the thermostat up, there is a "click" but the fan does not come on. This is a normal condition. The click you here is the gas valve opening to allow gas into the burning chamber. There should be a delay of 30 seconds to a minute before the fan is supposed to come on. But because of my unfamiliarity with these types of units, I'm not sure there is a fan temperature control on these units. But regardless there should be power to the fan when the fan is supposed to be on. A 120V tester will be required to check this. If there is power to the fan, then the problem probably is the fan motor itself. If there isn't power to the fan motor, then the problem is with a relay control that sends the power to the fan motor. Hope this helps.
