OMG !! HELLO DARIN !! MY MAN, YOU ARE A ABSOLUTE SAINT !! THRU YOUR VIDEOS, MY FURNACE IS RUNNING SO QUIETLY, THAT IT SCARES ME !!! LOL I DON'T HEAR IT RUMBLE, BIG WOOOSH WHEN IT IGNITES. I ALMOST WANTED TO MAKE A VIDEO FOR YOU, AS I RAN INTO A " ANTIVIBRATION STRAP " THAT HELPS HOLD THE MOTOR IN THE BRACKET AND NOT ENOUGH ROOM TO MOVE THE GAS LINE BACK TO BE ABLE TO EASILY REMOVE THE BURNER HEAD ASMBLY., THE ONLY OTHER THING THAT I HAVEN'T DONE IS HOOK UP A NEW DIGITAL THERMOSTAT, AS MY SETUP RUNS THRU A CONTROL SYSTEM 6.5 V THRU 2 TEMP. HEADS COMBINING THE 12.9 THAT'S ON MY SYSTEM. YOU ARE THE VERY BEST OUT THERE, AND I'VE WATCHED TONS OF VIDEOS. ALSO, THE GAL AT YOUR OFFICE IS A ANGEL, WHO GAVE ME PART NUMBERS AND RELAYED MESSAGES FROM ME TO YOU.
IF YOU EVER NEED A REFERENCE,
PLEASE DON'T HESITATE TO GIVE ME A CALL !! GOD BLESS YOU AND
MY RV WORKS !!!

Thank you for making such great informative videos. Couple years ago I bought my first travel trailer from a shady guy. He knew just how to hide all the problems with all the appliances. I was the perfect target for him having an excited wife looking at it with me and not knowing anything about rvs at all!!! With your videos I’ve managed to fix all my appliances except my furnace. It’s next on my list this weekend!!

[rickmathews]

This is why I call you the RV professor!

[edwardmiller]

Your vids are invaluable! I'm in the engine building biz for about 40 years, but electrical is NOT my forte, and you explain it in a way that this self-taught mechanical engineer can understand. I need to diag my own heater, and this will help tremendously. ty

Darren Thank You for this fantastic video on Furnace Theory of Operation and thorough discussion on each component's operation. These videos are informative, educational and for a DIY RV owner, You Make Me a Happy Camper!

[georgebaker]

My name is JR this video did help my with my problem on my sf 35 thanks for your how well you do your information video. The igniter on my heater was bad on the end and tip broke off by the time I took it out. Great job keep up the good work thank you JR.

[leebiggs]

Thanks for the info Darren. I used one of your videos last spring to diagnose the same Suburban 35 furnace in my trailer. It had occasionally not ignited when there was call for flame, eventually it wouldn't light at all. Found it was never opening the gas valve, no 12v to the valve. When I used a power probe the valve would work just fine. Being an electronics tech I thought, hey I'll just replace the relay on the board! No dice, no electronics suppliers had any stock unless a minimum order of 1000 each! It was cheaper to put in a Dinosaur Electronics board, furnace has been happy ever since. Thanks for your videos! The wife and I really need to visit PA and the Olympic Peninsula again soon. Hello from Snohomish county!

[tynewbold]

Your timing is amazing, as I’ve come across issues in my rv I go to see what you have on YouTube about the topic and of course you post exactly what I need around the time I need it. Always helpful and you’re much appreciated. Never hold back, thank you for your content!

[thomasgogan]

Darren, thank you for all your knowledge and advice. I have a small RV repair shop in Mt. and alot of your knowledge, tricks and tips have saved me some headaches, keep up the great work

[jewelornawatterson]

Darren You Rock!!!! Thank you so so We get to go to the Fisherman’s Festival in Bodega Bay, CA this weekend because YOU helped my Guy fix our heater💞💞💞thank You so much for all of your absolutely amazing guidance 🙏

[tzairvalencia]

Great video!!
You are an AWESOME TEACHER!!
Thank you!!

[justingoodwin]

I couldn't find the link below to find where to purchase the test lead kit that you we're referring too? It's not on t3.

[knutblaise]

I saw a youtuber couple, "Called To Wander", that are having problems with their fridge. I pointed them to your 21 video fridge playlist and suggested that maybe you guys could do a collaboration video if they can't get it working (they could post, you could download and repost with your commentary).

[jsteele]

really enjoyed this video thank you so much for sharing this video with me . I'm trying to get my first
motorhome. I've worked hard all my life and d*mn it I want the see the USA. It has taken me several years
to get to this point. I told my wife that I would never leave as long as my mother was living. Well she left us
close to a year ago. We sold the family farm and now getting our house it top shape to be able to rent it out.
My wife and I agree we never want to be with out a home. If we do this for 4 to 5 years and do not wish to live
this life anymore then we still have our house a home to go back to. I just do not want to have to call a service person
every time we have a problem. Also if I do decide to call a service person because I just do not want to fix it. At least
I will have some Ideal by the sound it is making and yes I will break out my fluke it he comes up with some bull shit of
a cost and prove to him what the problem is. I'm 66 years old and not stupid so do not treat me that way. I do not mind
paying a person for his time to honestly repair my motorhome. Any body that does this for a living deserves to be paid
for his training and knowledge. So getting back the subject thank you so much from my wife and I ! ! ! ! ! ! ! ! ! ! ! !

[dirksimmang]

i am smittimg with your videos...
can stop watching, can't get enough of them ....🤩

[andrewgibb]

Awesome video!! Please do a similar video for AC problems. Your videos are the best I’ve found. I’m a DIYer and trying to teach myself how to maintain my new RV

[cameronculp]

I haven't seen the comment yet, but it would be nice to see the video talking about the capping of the other blue wire. My understanding from school was that all furnaces had the 2 blue wires no matter the AC unit. please explain thank you!

[lanedelker]

I just found your site and started watching you for about the last month. These videos are great. You have a knack for demonstrating and then fixing these problems. While traveling to Tennessee last year, we suffered a total loss of 12v power sometime in the last 3 hours of our trip. I tried to fix it my
self. I just couldn't quite put all of the pieces together. I found a great repair shop in Lebanon Tn. just east of Nashville. Greg not only took the time to fix me up, he taught me a great lesson while doing it. I am hooked on learning this stuff. I plan to take some courses late this year in Athens, Texas. Now that I'm retired from Ma Bell, I am seriously considering becoming a traveling repair tech part-time. I love your content. Thank you so much. Maybe some tips and pointers about being a traveling tech?
