I see now why the plug for the engine block heater is unplugged from the factory.
With breaker On, there is always 120V at plug does not matter that it shows Off/On on Silverleaf.

Only way to kill power to the plug is to turn the breaker off.

Has others actually tested this with a plug in tester?

Are you sure you don't have a switch for it somewhere? The Dutch Stars have a switch in the cabinet above the steering wheel. I don't have Silverleaf, but if it's controlling it, there must be an error or a setting that's off.

The relay for the block heater is mounted at the top of the breaker box. Do you hear it engage/disengage when you toggle the block heater on/off via Silverleaf?

Also check your Silverleaf configuration under the Monitor Monitor Configuration page. There is a Block Heater instance number? Mine is set to 1.

Ordered the relay from Newmar.

Thanks for the help!

Relay came in yesterday afternoon.

Turned all power off and replaced relay.
Settings on Silverleaf are set for 1 and back to square one.

Testing both Silverleaf displays engine block heater off/grey still have 115V to engine block heater plug tried them both on/green and still power to engine block heater plug.

Wired it correctly, I give up and not worth the cost when we are up in Nappanne later to have corrected.
I will just use the breaker, same as I do when I connect/disconnect at a campground or home.

Forgot to mention while power was off tested relay with Fluke. No matter with switch on or off fluke would beep as if relay was not even there.

Went through this with my 2012 Essex, same problem, 3 people at Silverleaf was involved, Art was at the front........ Ask them about changing the instance number to another number to see if it would work as it should, everyone looked the print's over and said changing the instance would not affect anything at all..........Flyboy warned me......
So I changed the instance one at a time, when I got to 4 the Silverleaf panel(block heater) and the outlet in the engine compartment worked as it should..............

Next day my AC unit's started to Shed..........the TM 250 controller was messed up, Silverleaf swore it was just a cowardice, I didn't buy that........
Long story short after 7 TM 250 controller's, a 300 mile trip to a fellow Newmar owner that had the onmiscope program, and talked to Silverleaf when hooked up, they started sending the controller's.........
Every controller I received had a different problem.............something didn't work with every new controller........(Block heater set back to 1) finally after the 6th one was faulty, I called and with Mark at Silverleaf on the phone, I asked him to take a 250 and bench test it, as the just clear a controller and drag and drop the file on it per the Coach.

In a short bit, Mark said "Oh My"........ the file for your Essex must be corrupt......
Mark took the time to re due the program file for my model year Essex, and loaded it on the 250 and bench checked it out.........That 7th controller worked as should for everything except the block heater........he said he would have to work on that futher......A month after the trip to Ohio where the fella hooked his Onmiscope up to my Coach called me and said he got a email that there was a patch for the Onmiscope program to correct the Block Heater and Sliverleaf panel not working together..........

He said if I wanted to come back out, even meet me half way he said he would rewrite the 250 controller for me............
I said no thanks........everything has and still working as it should and don't want to take the chance after this 7 month go around...........if I am some where I need the block heater..........I can plug it in the night before..........I keep the block heater breaker off in the panel.
I did test out the relay you replaced and it was working, opening and closing, it just wasn't getting the proper signal from the 250 controller as there is a program fault in it.

Hope this give you some insite into your block heater problem and what it is going to take to get it operating as it should.

Thanks for this write up, never did change my instance from the 1 setting. Now 2nd relay does not work, so before I mess anything else up, I will just plug in block heater and use breaker.
This must be a known problem as most Newmar DP engine bays the block heater is unplugged!

Easy to test the relay. Just connect to the battery 12V and ground and see if it clicks. Can also hook multimeter to the relay terminals to verify continuity.

Found my TM-250 was not working was shedding front AC and erroneous outside temperature.
Just installed the new one and under load shedding it still indicated Off for Engine Block heater.
I plugged the new TM-250 as I unplugged the old.
Seen some wires that never were connected, I am beginning to think this could be my problem.

Is the outlet for the block heater still hot all the time with the new TM-250 plugged in David? As the old one was?
There are extra wire's with plug's on them on my Essex hanging up there buy the TM250 also.........

Yes the engine block heater is still hot if breaker is on and Silverleaf does not matter, Silverleaf sent me a wiring diagram and it looks as though I should maybe move my bottom connectors over to 1-5 and 6-10 and not use the 11-15 plug.
I just replicated on change out to how it was, but Silverleaf did state if 1-5 was not used the switch on Silverleaf for engine block heater would never work.
Can others look at their TM-250 and see how how it is wired across the bottom?
Thanks David!

Palehorse89,

What connections are used on your TM-250? I’m wondering if that’s the reason we could not get anything to work right when looking at it with Omniscope. Mine uses ports 1-5 and 11-15, heater on instance 1, and is working. Found that was different than some out there that may be wrong from the factory.
