Help Replacing Coleman Mach 15 48004-969 A/C with Heat Pump

Tammy Jo Kerney — Wed, 21 Jun 2023 01:17:20 +0000

Good Morning, I hope all are well. It is a toasty 100 plus this week in South Texas. We did our Paul Newman A/C modification and have been extremely Thankful! Huge difference! However, we have our AC / heat pump rolling over to die. Perfect timing of course! LOL We have a 2014 Redwood 38gk. Our Back A/C with heat pump is the 48004-969 Coleman Mach 15. Our front A/C only is a Coleman 48254-969 and looks like it won't last much longer either. Any recommendations on changing and or upgrading the Coleman Mach units? We have a regular AC in the front and a heat pump in the rear. Stay with Coleman? Something else? Any extra parts we will need to change out? Tips and Tricks?Where to order from? Warranty? Thoughts? Thanks

Thermostat Activates both heat pump and Propane at same time:

We have a 2013 31sl with a heat pump. Problem is that the propane heater also comes on when I slide the switch all the ways over to “Elec. Heat.” Don’t remember it doing that last year. I’m figuring that this is a thermostat problem seeing how both the propane heater and AC units are working correctly on the other thermostat settings. Q. has anyone one else had to replace their thermostat? Seems like a thermostat should not have this type of issue?? Q. If I do replace the thermostat is it a simple modular plug swap out near the thermostat itself? I didn’t want to chance breaking any of the solder points on the thermostat circuit board so I’ve left it alone until I have a replacement in hand. I looks like a single bundled wire running into the wall behind the thermostat. I hoping that there’s modular plugs hidden in the wall behind the thermostat that make this an easy swap out?? Q. The current unit is a RVComfort.hp unit. Is there a better more durable unit out there that I should use for the replacement? Thanks for any input...

AC

Not sure, but I think I may have to replace my two AC units. Is it possible to get two units with heat pumps. I know the LR AC has one, but what about the bedroom unit. Would you advise me on the possibility of this?

Help! I am missing an AC vent and don't know where to find a replacement

We recently purchased a 2011 Redwood 36RE. It's in great condition except I'm missing one of the return air vent grills in the ceiling. I haven't been able to find this part online. Can anyone help? Thanks! 626

Bedroom AC

Jim — Sun, 19 May 2019 02:40:53 +0000

I just noticed that my second AC unit over the bedroom is not working. I am not getting the fan or motor to work. I checked the fuse box and all seems normal there. I played around with the thermostat and switched it off and on, fan and no fan with no luck. Any ideas? As it starts getting warmer this will be a problem.

Can you run basement heater when driving? I believe it is the red toggle switch. Heading home and weather is supposed to be in 30's. Thanks Dee

Addition of 3rd AC unit - questions?

Jim — Fri, 15 Mar 2019 00:11:14 +0000

Hello. With summer just around the corner I've been considering the addition of the 3rd AC unit on my 2018GK. I have some question for those of you that have the 3rd AC unit or who have installed one. My AC section of my power distribution panel is full so I cannot add the breaker there. For those who have the 3rd AC unit from the factory where is the breaker installed? If you added the 3rd unit at the dealer how/where did they install the breaker? I'm pretty sure I need to upgrade my Power Control System module and control panel as well to accommodate the 3rd AC unit. My current PCS only controls two AC units and the electric water heater. For those of you that have the 3rd AC and the PCS could you post a pic of your PCS panel? Thank you! 587,588

Woke up to discover my heat pump is blowing cold air. Planning to cut shore power to see if it will reset the unit. I would appreciate any other suggestions you might have. Airxcel Model #48004-869 Thanks
