<h3>About MC Enterprises</h3><p>MC Enterprises has built a well-earned reputation as a go-to source for aftermarket replacement parts aimed at RV owners and technicians. Rather than manufacturing whole appliances, MC Enterprises focuses on the components that keep existing RV systems running — the circuit boards, blower motors, control modules, and ignition kits that are often difficult to source directly from original equipment manufacturers. For anyone maintaining a motorhome, travel trailer, or fifth wheel, that kind of focused parts availability can be the difference between a quick roadside fix and a lengthy repair delay.</p><p>The brand's catalog spans the core mechanical and comfort systems found in virtually every RV: furnaces, water heaters, refrigerators, and HVAC equipment. MC Enterprises produces aftermarket replacements compatible with some of the most common OEM brands in the industry, including Dometic (Atwood), Suburban, and Norcold — making their parts a practical solution for aging appliances where original components may be discontinued or hard to find.</p><h3>HVAC Blower Motors</h3><p>One of MC Enterprises' strongest product areas is <a href="/5807-mc-hvac-blower-motor-6916">HVAC blower motors</a>. These components are critical to RV furnace operation — the blower motor drives both the blower wheel and the combustion air wheel, and the furnace simply won't run without a functioning one. MC Enterprises offers direct-fit replacement blower motors compatible with popular Suburban and Hydroflame furnace models, giving DIY repair technicians and mobile RV service pros alike a reliable, cost-effective alternative to OEM parts.</p><h3>Water Heater Parts &amp; Control Boards</h3><p>MC Enterprises is also a recognized name in <a href="/5807-mc-water-heaters-201162">water heater</a> replacement parts. Their lineup includes ignition control circuit boards and igniter kits designed to fit a wide range of Dometic (Atwood) and Suburban RV water heater models. These boards handle the critical task of sending the ignition signal to the spark probe, initiating propane combustion to heat water. Having an accurate replacement board that matches the original wiring configuration is essential — and MC Enterprises has developed a reputation for delivering just that.</p><h3>HVAC Control Modules</h3><p>Rounding out the brand's climate-control offerings are <a href="/5807-mc-hvac-control-module-47959">HVAC control modules</a> and ignition circuit boards. These electronic components act as the brain of an RV's heating system, regulating ignition sequences, monitoring safety inputs, and managing overall furnace operation. MC Enterprises' aftermarket control boards are engineered to integrate seamlessly with existing RV appliance wiring, making them a practical choice when an original control module fails and an OEM replacement is no longer available.</p><h3>Why Choose MC Enterprises?</h3><ul style="list-style:disc"><li><strong>Wide OEM compatibility:</strong> Parts designed to work with Dometic, Atwood, Suburban, and Norcold appliances</li><li><strong>Focused on hard-to-find components:</strong> Specializes in circuit boards and motors that are often discontinued by original manufacturers</li><li><strong>DIY-friendly:</strong> Replacement parts are engineered for straightforward installation by RV owners and mobile technicians</li><li><strong>Broad appliance coverage:</strong> From furnace blower motors to water heater ignition kits, a single brand covers multiple RV systems</li></ul><p>Whether you are troubleshooting a furnace that won't ignite, a water heater that fails to light, or an HVAC system with erratic behavior, MC Enterprises offers targeted, affordable solutions that get RV systems back online without the wait or expense of OEM sourcing.</p>

Product Details

The MC 232503MC is a furnace limit switch designed as an aftermarket replacement for Suburban RV furnaces. This critical safety component protects your furnace from overheating by automatically shutting down the system when temperatures exceed safe operating limits.

Key Features:

  • 150°F temperature rating for precise overheat protection
  • Red color-coded identification dot for easy recognition
  • Direct replacement for Suburban furnace models SF-20 and SF-20F (above serial number 921403895)
  • Also fits SF-20Q and SF-20FQ models
  • Designed specifically for RV furnace applications

The limit switch is positioned at a critical location above the heat chamber and acts as a fail-safe device to prevent dangerous overheating conditions. When replacing a limit switch, it is essential to use the correctly rated switch for your specific furnace model to ensure proper safety protection. This switch is an exact-fit replacement that installs directly in place of the original equipment, restoring your furnace to safe, reliable operation.

Site was having problems. I was asked to reload in a few minutes. :-(

shopping was easy, via quick Google search for part number, found that Autoplicity has cheapest price available for this item. Will see how shipping proceeds and speed thereof.

thanks!!

I have called three times to ask a question about the item I ordered but each time, after being on hold, when I got to be the next call in line, I got hung up on... all three times! So now I have ordered and REALLY hope I am pleased.

Adequate.

Ordered a strut before, seems like a good site, just that their shipping doesnt update on their site well. called and they got me a tracking number

Prompt on shipping order and delivery. I will use them again with future purchases

I saved a lot on the PIAA 520 ATP lights I purchased for my FJ Cruiser and I can say that because I looked everywhere. A couple hours after placing my order I decided t call and ask to pay for expedited shipping. I had the BEST customer service experience! As I build my FJ, I will buy everything I can HERE.
