My wife wanted one, and I told her she already had one in the convection oven. She tried it, and it works awesome. Great! So I bought one for nothing? :SRe: Sofa Bed Mattress:S As happy2rv pointed out, the mattress is in fact a full, NOT a queen. Now able to find many that will fit. Thanks!Sofa Bed MattressI’m looking to replace the sofa bed mattress in our RV. We’ve tried two different air mattresses, but the sofa bed mechanism eventually tore a hole in them, so air mattresses are no longer an option. I’ve hoping to find a foam mattress for better comfort over the OE mattress, but I can’t find one to fit our sofa bed for under $400. I really don’t want to spend that kind of money. Our current mattress is a short queen, 71"x53". Any recommendations? Thanks.Re: Malfunctioning Coleman ThermostatNo worries Doug, thanks for your help.Re: Malfunctioning Coleman ThermostatThanks for the reply, even if it was somewhat insulting. Please show me where I said I wouldn't consider a new system. I merely said in other words that I was getting ready for a re-paint, so I would attempt an easy fix first, due to the cost. With or without the cost of a paint job, most people would do the same. To bash someone because they want to attempt the easiest/least expensive fix first just doesn't make sense. Regardless, thank you for your information.Re: What is your favorite YouTube RV channel?As my forum name implies, I love gadgets, so I enjoy The RV Geeks, Love Your RV and Long Long Honeymoon. I use to watch RV Love, but their latest video on RV tires contained bogus information while omitting important info at the same time. No longer a fan.Re: Correct AIr filterFleetwood Couple is correct, unless you're running a K&N filter, the filter element and housing are all one unit. Here are the part numbers for my C7: Baldwin PA3493 FAR 114880-003Re: Malfunctioning Coleman ThermostatA very expensive option, but I'm sure that would work. I think I'll give your first suggestion a try first. I'm getting ready to dump a bundle in a new full body paint job, so replacing both A/C's isn't doable right now. May I ask why you suggested Dometic instead of Coleman?Re: Malfunctioning Coleman ThermostatDoug, Thanks for the reply. I made a typo in my OP, I only have 2 A/C units, not 3. I just fixed the typo. :S The fix sounds complicated so I will forward it to my mobile RV tech and see if he is willing to attempt it. Thanks again.Malfunctioning Coleman ThermostatMy 2005 motorhome has two Coleman Mach 2 A/C units controlled by a single Coleman RV Comfort ZC digital thermostat. Two to three times a year, while running the A/C’s, our t-stat will make a popping noise and will instantly give a digital readout of “00”. This effectively shuts off any cooling as it turns off the A/C compressors. It does however allow the A/C fans to continue running. If we are home this is no big deal, as we can reset the t-stat by momentarily turning off the house batteries, but this could spell disaster for our dog in hot weather if we are away. When this first started happening, I contacted Coleman and got in touch with one of their engineers. The engineer said that although this problem is rare, it does happen from time to time on some RV’s. He told me that there is some sort of 12V radio frequency interference inside my RV, which is causing the thermostat to go into diagnostic mode. He kindly sent me the latest t-stat and radio noise choke filter free of charge. When this did nothing I called him back. He told me the following items could be causing the interference: fluorescent tube lighting, TV antenna booster, bad inverter/charger, CB radio. I removed all of my fluorescent tube lighting and replaced them with LED strips. I replaced my OE TV antenna booster with a King Controls Jack antenna and booster (I power down the booster when the RV is unattended). I eventually replaced my Xantrex Freedom MSW inverter/charger when it quit working, with a Magnum PSW inverter/charger. My CB radio is a non-issue as it is only used while traveling and even then, rarely. Another RV tech told me that any battery charger can emit a radio frequency, so he told me to disable my Magnum’s battery charger when it is not needed, which I have. Unfortunately, NONE of the above measures have solved my problem. I have been dealing with this issue for years. Someone recommended replacing the Coleman t-stat with a residential, but I have two zones with remote sensors for heating & cooling, so I don’t know if a residential will work. Any suggestions?
