  1. 1980 Dolphin duotherm heater After lighting the pilot, following the instructions printed in the heater cover, it just blows out. The thermocouple is positioned well but the flame seems to evaporate after about 45 seconds as if it's not getting enough oxygen. Any suggestions? Thanks! Rachel
  2. My furnace was making a horrible screeching noise for the first 5 minutes of use ..each time I used it. The fix? Simple.. I used 3 in 1 oil oN the fan motor. getting to the fan motor.. not so simple. I finally got the courage to dig into The furnace..pulling it from it’s spot under the fridge (I have a model 200 dolphin 1991).. To remove the furnace, first go outside and unscrew and remove rhe exhaust vent. Make sure that you carefully remove any caulking around the vent, and don’t forget to accidentally drop the screwdriver..so that it can roll directly under your rv and settle in the exact center. then go inside of the rv, and remove the cover off of the heater. Then remove the two screws from the frame (where it attaches to the wood) and then get a paper towel to wipe up the blood and to wrap the cut on your right hand. Its at this s time, that you want to have a glass of wine (beer can be substituted if necessary ) ..then using a 3/4” wrench, start to remove the propane coupling.. make sure that you stop, run outside to double check that the propane is turned off..then drink more wine.. then either unhook your coach battery or remove the 15 amp fuse that controls the heater . MAKE SURE YOU ARE NOT PLUGGED INTO SHORE POWER. THEN remove the propane coupling.. it’s at this point that you should take a break. the next morning.. after coffee.. and dealing with the cat.. remove any drawers next to the unit, so you can have access to the back and sides.. you will need to loosen the unit by pushing it from the side, rocking it as best you can while cussing loudly .. cussing does help. Once loose, just slide the unit forward ....then you need to mark and cut the wires.. I suggest taking pictures so you can make sure to reattach them correctly.... Then you can slide it forward and out. The vent pipe is just pushed in and will pull free. after that.. it’s just removing a few screws.. cleaning out all the mud, dirt and bugs, and oiling the unit... test the fan motor by hooking it to a 12v.. . ( or just replace the motor ..it’s just around $100).. then put it back together, in reverse order...making sure to cuss and stop to drink more wine. After that.. it’s just posting it on social media.. oh, and more wine.
  3. Hey, all. I would like to replace my DuoTherm with an Electronic Ignition furnace. My DuoTherm measurements are 12"x12"x15.25", with a 4 inch reach to outside duct flange. Any idea of a brand that makes them that size? i have been looking, but coming up empty.
  4. Very simple upgrade to the old-school, round thermostats that you find in most vintage RVs. Much easier to read/set accurate temps and takes less than 5 minutes to do the swap: 2 wires and 2 mounting screws. Emerson 1E78-140 (found mine for $18 on eBay w/shipping).
  5. Hey! I am traying to start up my furnace in my 1983 Sunrader for the first time ( My first time its the original suburban furnace ) Ive checked all my propane lines for leaks and have two full propane tanks. What I have done to try to start the furnace is obviously open propane tank, put the thermostat up to a higher temperature and flipped the little off switch to on position. What happens is i get a hum from the furnace... thats it. I do not feel any blowing air, hot or cold coming through the vents. Is there a problem or am I not using it right? Does the furnace need to be manually lit? What am I doing wrong? Thanks!
  6. Hello fellow Toyota Motorhomers, I've been looking for a furnace to put in my '91 Dolphin and found an Atwood on Craigslist for $100. The owner can only tell me that it is a 1995, it works well, and came from a small camper. The model # is not listed on it, only a serial number. It looks like it's in great shape from photos. Mainly, I'm wondering if much has changed with the Atwood since 1995...pilot light vs electric, amp usage, etc? Or if there's anything else I should be concernaed about? My Dolphin came without a furnace so I have no experience with these little heaters. Any advice or input is appreciated. Thanks!
  7. The furnace in my 1986 Class C Dolphin stopped firing. The blower comes on when heat is called for, but the burner doesn't fire. I pulled the igniter and set the thermostat to call for heat, but I didn't see the igniter fire. Perhaps it doesn't work this way, but that is what I tried. When the furnace was working there was a ( less than 30 second) delay between the blower starting and the burner firing. Can anyone please give me some insight or a link to a troubleshooting/repair guide.? The information on a tag on this unit says: Terralab Engineering S/N 1215014 Gas Fired Heating Unit Thanks.
  8. OK, this is odd, at least to me. It's been cold so the furnace has been running at night. Two nights ago I woke up because it was getting chilly. The furnace fan was running but no heat. Obviously the sparker either wasn't firing, or the gas valve had gone bad. So, I got out my little Coleman catalytic heater, fired it up, and went back to sleep, figuring I would troubleshoot in the morning. When I got up I made some coffee and decided to start the furnace again to see if I could get an idea of what was happening. Fan started and a few seconds later, CLICK goes the sparker and the damn thing fires right up and starts putting out heat, like it never had a problem. I take the facia off, turn it on and off a few times, observe that the piezo-type sparker is working and that its getting LP, and wonder WTF? It's firing up like it never had a problem. Fast forward to last night. I turned on the furnace, went to sleep, and again, I wake up in the middle of the night because its chilly and the furnace is just blowing cold air. I get up, shut it off, turn it back on, and everything kicks on and I have heat. Again, WTF? Anybody have any idea? I first thought it would be a breaker to the piezo tripping, but I would have to reset it, unless it has an internal of some type, which I doubt. Only other thing I can figure is maybe a draft disrupts the lighting of the burner, maybe because it was windy outside? That doesn't make a whole lot of sense either though. It has to be the gas valve sticking or something, right? Anybody run across this before?
