Radiant floor heat not working in my 2018 Newmar London Aire

Shore power on? Salesmen switch on? All areas not working? Breakers, GFCIs reset?

Yes, yes and only one area not working (bedroom). All breakers have been reset. I have one GFCI not working (master bathroom)

 

[Sealyn]

Bath GFCI might be the issue.

 

[Jerstaci]

Bath GFCI might be the issue.

I have replaced the GFCI and the new one does not work either, any suggestions

That means it is not getting power, so it won't reset. You have to find what is feeding it and what else is not working.

Most times the gfci is not at the end of a run. It is protecting other things in a run.

Is there anything else not working, oasis AC, AC unit. Check load shed on Silverleaf. My TM250 just died and I lost the #1 air conditioner, #1 Oasis AC and rear floor heat. Silverleaf customer service was very helpful in diagnosis

Basing this on my 2017 DS 4369, but it is probably almost identical. My system has buttons that control the different areas for the floor heat. Those areas receive their heat from a series of fluid pumps. On my system, the box with the pumps in it is mounted on the wall behind the halfway thru compartment that is the right side of the coach just in front of the pegboard bay. It is a box that is the same color as the oasis burner section and roughly half the size.

Shortly after I got my coach, one of those pumps went bad and I had to replace it. Bit of a pain in the butt, but doable for anyone with a bit of mechanical skills, a lack of claustrophobia and a bachelors degree in contortion. If I remember correctly, I was able to find out that the pump was bad by checking out the lights on the oasis junction box that should be mounted right next to the oasis burner can. Mine is on high on the wall aft of it. It has a bunch of lights. Look there to see if any lights are on (I think 1 red light is normally on).

If you only have partial areas not working, I would bet that one of your pumps has gone bad. For reference, I think that there are 3 pumps, 2 are called 1 thing and the third is called something else. At least 1 is called the summer loop pump.

When I had my issue, I contacted Oasis and they talked me thru the troubleshooting to verify a bad pump. I got a new pump thru them and replaced it. Been running it since then with no issues.

Floor heat is electric and has nothing to do with Oasis.

 

[Canaddar]

Yes it does. Your oasis system has several options to provide heat. A single electric heating element, a dual electric heating element, a diesel fuel provided heating.....or any combination of them. Sorry about the bold, but that is how it came with a cut and paste.

How does an RV Oasis Hot Water System work?​

The Oasis Heating system uses a diesel burner controlled by a multi-function controller as a primary source to heat a coolant fluid (anti-freeze and water). It also uses two 1500-watt AC immersion elements as secondary heat sources. The system heats the fluid which can then be circulated to meet all heating needs. This includes hot water demand as well as coach heating.

@Canaddar , the discussion is speaking to floor heating…the heating system that heats the floor tiles. Newmar floor heating is an electric grid underneath the tiles.

Evidently, floor heat is linked to oasis. Or he would not have this experience to tell.

Floor heat may well be electric, but what if the system fails to see one system as a backup in case of failure? Faulty programming? Maybe! It may have been fixed with a climate control update, but if the issue was resolved as this comment stated, it would be an error to denigh it as a possible solution!!!

 

[NWIP]

Oasis provides heat via the furnace selection as he states but floor heat is strictly provided via electrics as stated by @Neemer

Holy c__p batman!!! Vindicated again! One of those elements requires 3× the power of my A/C unit. I can't consider running that on solar, let alone floor heating off grid!!! And one wonders why I discount what building professionals say, about the way it should be done in RVs!!!

Just saying!!!
