Suburban RP-35FQ 35,000 BTU/h RV Replacement Core for Suburban Furnace Series F-42F, SF-35F, SF-35FQ, SF-42FQ, SF-FQ (2610A)

I received this unit yesterday, installed it today. It was a perfect swap. Easy to install. On my motorhome you must take the whole furnace box out as the old unit and new unit slide out from the back. Once the new furnace was in, turned on the thremostate and it lit right off. It is much quieter that my old one. The furnace core comes with the circuit board. And sail switch installed. So far, very happy.

Works as it should but a bit noisy. Air flow is anazing

As described. Works flawless.

Purchased replacement unit for my Suburban furnace installed it last October and used it a couple days and then closed it for the winter season. Opened the unit up this April and started the furnace and it ran a couple hours and quit. Attempted to get a replacement thru Amazon and was given information on testing the unit and hired a professional Furnace repair service who tested the unit and found a defective control board and advised me to get a replacement from the manufacture and I am still trying to get one since I purchased the unit from Amazon the manufacture wants Amazon to send me the replacement. Called Amazon today and was advised I will get an email from the manufacture tomorrow. Will wait to see what that says. Paid $463.82 for this unit with a 2 year warranty and it needs a part that cost less than $40.00 and I paid the service guy $149.00 to test it.

Works as it should.

Bought my new furnace in February of 2025 didn't make it one season before fan motor stopped working had to order a new fan motor NBK 20563 it the motor number for this unit motors are made in China hope that this one last more then a few months

Bought to replace furnace in 2020 Imagine design. Had RV repair do the actual replacement and it has worked good for close to a year now.

Been using it for a few months now and works great! Great price (around 400) for a new unit! You can re-use your old sheet metal enclosure, a DIY'er can swap em out.

Works great, pity I had to send the first one back. Very happy with the replacement.

Working fine for 2 months so far. Different location for propane inlet was the only issue for myself but was easily fixed

I kept on buying parts for my existing camper furnace. Got tired and started to look around online and stores within my area to only find it to be really expensive. This one came up on Amazon and I ordered it right away. This is a whole unit and goes in your existing case. Mine was SF-35F and I bought this and it fits perfectly. There are no issues and practically plug and play.

Unit arrived on time did a bench test to burn off factory oils Fresh 30lb.propane tank with fully charged 12volt battery Ifan starts right away. No spark will not fire Three tries no go rest .6more tries unit will not fire

The furnace was delayed in transit and took a week to get. The furnace came VERY well packaged. Fits perfectly into the housing . Works great. Things to keep in mind. My orginal furnace had the gas inlet at the front beside the circuit board. This furnace came with the gas inlet at the back of the furnace on the same side. So make sure you have enough gas line. Hope not to have to buy again but totally recommend. In the one picture Left is original and right is the new one. The other two pictures are of the new one.
