    We went out last weekend and the blower on my heater won't stop blowing. No heat just air. I turned off the on off switch, flipped the sink, under which there is a "kill all" switch and the blower kept going. Once I unplug or turn the converter to off it stops. Looking at the manual it seems it is the on/off switch or possibly a relay. Has this happened to anyone? Any Ideas? Thanks.

    There's a list of possibilities. I need more info.
    When previously, did you have the furnace running, a few days,weeks, months?
    Did it run well at that time?
    What's the make & model #?
    Did it attempt to light, did you hear a clicking noise?
    A relay keeps the blower running for about 2 min. after it is shut off. This is a safety to clear the firebox of hot air. It is just a time delay and does not know if the air is hot or cold. This should never be connected to the sink kill switch for obvious reasons.
    If you have a battery on the pu, unplugging or turning the converter off would not stop the blower. The delay time may have run out by the time you got there.

    I had the furnace running in spring and it did run well. This last outing the blower blew cool air non stop for 3 days. I did call the manufacturer who said it was a relay and I have not yet received the part. I hope to have the part and install this weekend. I will post back as to whether or not this fixes the problem. Thank you.

    It's either a relay or a short on the positive lead.

    Good luck.

    Your furnace requires 10.5-13.5 volts DC (battery) for the blower to open the sail switch and ignite the propane. After reaching temperature, the burner will stop, the fan will continue to run for a minute or two and shut down, only to come on again once the temperature goes below the thermostat setting.

    Please fully charge your battery, and disconnect it when not in use as your propane leak detector will draw it down in about 10-14 days as it is direct wired and on 24/7.

    From what you've posted, your battery is below the required 10.5 volts, so while the blower might work, there isn't the battery voltage to open the sail switch and ignite the furnace.

    Okay, disconnected the thermostat and blower stopped after a minute or 2. I Bought a new thermostat reconnected that and the fan/blower went back on, but heat did not kick in, turned off the thermostat and the blower kept blowing?????? Any more thoughts would help. thank you.
