When replacing old Laing sm-303 with newer model is it necessary to shut off water to heater before proceeding? Also, can old motor be replaced by han

Yes, there should be no water going to the plumbing for the motor when you replace it. I needed to use tools to help loosen the old and tighten the new motors. dm

Shut off the water that supplies the pump. You should then be able to unscrew the motor assembly from the housing by hand. Screw on the new motor assembly with the new seal which comes with the new unit.

The Ambient temperature is the NEMA insulation rating. (40 deg c) also added is the insulation Class. Class B is typical in small motors. With a class B rating the maximum operation temp would be 130 deg C or 266deg F. Also, the motor has a fan on the back of it to cool it. Lastly, the motor in not mounted inside the heating chamber.You will have no problems with this replacement. It worked great for me. See the link for more info on the NEMA ratings: http://www.engineeringtoolbox.com/nema-insulation-classes-d_734.html?v=155&units;=degC

I have not yet had to replace mine, but if/when that time comes I would think that some of heat gun elements offered on ebay, compatible w/ Liester or Bak Rion heating guns would work as a replacement. I second the recommendation to let the heat gun run on level zero to allow the element to cool after use. I just let it run until the gun nozzle is cool to the touch.

I have model # U4160H2R4 Type 7. I just compared the photos. Works like it's brand new. You will have to disassemble the bottom of the unit for the new install and clean out before installing the new parts. You will notice that the brush has two guide plates on both sides of the brush with the words old & new. I set it to the new setting. Installed the new belt and bag , and it works great ! About 30 minutes to change the parts out. Make sure you remove the side access cover for the belt, remove the old one and clean up the motor drive spindle of old rubber before installing the new one. I hope I have been helpful.

There are several heaters and depending upon the model/serial number the wattage will vary. The best thing to do is call Norcold Customer Services with your model and serial number and if you know the cooling unit number even better. It is located in the back of the fridge and you can see it from outside the coach/trailer. They will give you the correct part number for your unit - then order it on line via Amazon or E bay and save a bundle. It is not an easy job replacing it as the old unit is usually rusted in place- good luck. I accomplished the job and it works fine.

If your unit has a temp. control the unit will need the larger screens. I could not find my model#, so I called Nesco and I was told the model 3 is stamped on the side of the motor head. Without a magnifying glass, I could not read my model #. I have been out of town or I would have gotten back to you sooner. I will add, the screens are not dishwasher safe.

It is easier then the old one. When you take out the old one remember to take off the 90 degree elbow and use it on the bottom of the new one. This way you will have more room to turn it in the back of the compartment, if it is as small as mine was. The top line is hot and the lower line is cold. There should be a cover plate in the back of your existing unit, you need to take it off to access the water lines, it is a tight fit. One can be turned by hand, but the lower one (cold water) is a little difficult, you may have to use a wrench to get it to turn at first. I hope that this helps and is what you are asking.

Beverly, you didn't state your model or how old the unit, but one common weak link is the on/off switch may be faulty, the second primary failure mode would be the heater coil/thermostat and would generally be cheaper to buy a new one than try and fix. If you have a handyman around he should be able to check out the on/off switch.

We have used ours for 2 years now. So far no problem w/ the heater. We did have a problem where something got stuck and melted much of the unit. I contacted the manufacturer and they were very good about repairing my unit. I have actually had a couple of problems, the other was some board went out. Again, they were very good about replacing the board. I have not had a problem in a while, so I don't know if they would still be so good, but we do LOVE our machine!

The unit is operated on AC, but like most alliances, the AC in most cases is converted to DC. Regardless, the Unit needs to operate on AC in order for it to work. The Rheem's and other Electronic On-Demand Water Heaters only require a fraction of power to operate... the heat is provided by PL or Natural Gas, the fan takes the most, but will run on Modified Sine Wave Inverters. No other Brand On-Demand water heater will warranty if they run on Modified... they must be on Pure Sine Wave, or grid power, or Inverter style generators (with an "I" in the model number). So with folks that have older modified sine wave inverters, The Rheem is the only one that will operate and won't void the warranty.

The standard motor that comes with the unit has burned out on my last two units. I bought a whole new unit to replace the first and the motor burned up on it in two seasons. I only make ice cream on occaision and in no way over taxed the motor on either of the first two. I purchased this replacement motor on amazon and it says it has an industrial strength motor. I haven't use my new one yet, so I'm interested to see if it will ouitlast the others. I would suggest replacing the motor and making ice cream without delay. I'm figuring it's part of the cost of operation.

there are 2 aspects: electrical and plumbing. If you do not have the right guage wiring and breaker size then this electrical work has to be done. In addition you need a shutoff switch near the unit in case power has to be turned off to the unit. For the plumbing if the tankless is replacing and existing hot water heater that was in the same area, then the plumbing connections are more straight forward as described in the installation booklet. If the tankless is in a new location then there is a bunch of plumbing required. The installation booklet is pretty explicit on what is need and what connections are needed to the tankless. s

I visited several appliance repair and supplier sites looking for the model and part numbers for interchangeability. It appears that the replacement motors apply to many units. Instructions should have info about any particular wiring changes which will permit use in your unit. It was fairly straight forward.

I replaced a 9E with this unit. You can use the door you currently have and new hinge pins are included with the 10E. You will need to get either a single switch to go with your current gas switch or order the double Atwood switch as I did. You will need to run a single wire from the unit to the new switch you purchase. It is used to activate the water heater in electric mode. The 9E did not have this wire, only the gas wire/switch.

Call Masterbuilt customer service for replacement parts for the unit. I think I read somewhere that the newer models have replaceable heating elements. I would call the company just to be safe.

I have a Bradford White 40 gal heater3500w-4500w and the element fit just like the old one. I reccomend getting the socket tool to remove and install the element. I also replaced both elements. I have hot water again like it was new. I also found out that you need to drain the tank every 2-4 months to prevent mineral build up. That is what caused mine to fail.
