    Thanks Michael for your reply, I will need to go on to Google again to first find out what it looks like and replace it if parts still available on the market. Thanks again. David

    Check your thermostat and make sure it's not tripping of there. So, the burner comes on to heat up the exchanger then a minute or two later your fan should come on, correct? How long after the indoor fan turns on does the unit shut down?

    It sounds like you combustion chamber temp switch has failed. It should heat up the combustion chamber then when it gets to a certain temperature, it should close and turn your fan on. It sounds like it's not closing and then the heater turns off on excessive heat high limit switch. Your going to have to locate the bad switch and replace it. Sorry it took so long to respond, I was out of the country

Where to find fuses. My dryer is not heating up.

Does your dryer have power? If yes, then check (1) the flow of air outside the house from your dryer tube and (2) your circuit breaker panel for each circuit in the house (I've not seen fuses/breakers built into dryers -- though that could change). Then check (3) your heating element, (4) thermostat, (5) high-temp thermal cutoff switch, and (6) for debris in the air flow path to / from from the centrifugal fan.

HE4 propane dryer wont heat, how do I get the codes display?

Sounds like a clogged exhaust duct or vent. If not venting properly, most dryers will turn the heat off, for safety reasons.
Go for the easy fix first. Before removing your exhaust ducts from the dryer, look for any kinks that may cause blockage. Clean out the duct of any lint or water that may have accumulated. Check the vent on the outside of the house and make sure that its not clogged and opening properly.

Vulcan-Bonaire : summer breeze

This unit is a cooling unit only. I don't know what switch you are looking at but I don't think it's for the evap. cooler(swamp cooler). I am in the Phoenix, Arizona area and it's very common to have a evap. cooler and a seperate heat/cool system as on the hottest days the evap. cooler doesn't cool enough. I hope this helps. Please give me a positive rating. Thank you.
