Sunheat SH1500 heater starts popping when heated up and cord gets hot to touch.

Firstly, you need to take off of high and keep it on the low setting. And don't use an extension cord' it don
t like that. The popping sounds is from the unit expanding from too much heat. No problem there, just don't force the heat so much. If you don't turn it off of high, you're going to burn it out. It'll run longer on a lower setting to give you the heat and will last a looooooooong time.

Why doesn't fan start?

Fan operation should be less noisy after it has been replaced.

What does a E2 mode mean how do I reset?

The '2' in E2 seems to refer to list of conditions under 'Troubleshooting' in the user manual for this product. The version of the manual that I have found claims that in this condition the problem is: "The amount of heated air exiting the front of the portable heater is reduced."
The solution is to: "Check the electrostatic filter to make sure it is free of dust and dirt. Also check the front grill and rear air intake to make sure it is not being blocked by any kind of debris."by BillBell

How can I fix My 2006 Honda pilots noisy Ac fan .

You have one of two problems causing a noisy heater fan. The bearing in the fan motor is getting bad or something has fallen down into the heater box ( napkin/paper) and compromising the spinning of the fan cage. You will have to remove the fan assembly and inspect for foreign debris and/or bad fan motor bearing

How to cure a noisy fan ?

Hiya! These fan units are a royal pain in the neck!

What you need to do, is get to the fan unit, remove the motor from the blade (they usually have a twist and lock bracket held on by a single screw)

The motors for the blowers are just simple shaded pole motors but these often dry out due to dust, and heat over time.

The best cure is to unscrew the motor and pull the shaft and rotor off of the front and back bearings... clean the shaft thoroughly of any debris and set aside.
Then, you want some light sewing machine oil (easily obtainable in most fabric stores) and you want to drip it around the outside of each bearing so the oil absorbs into the pads around the outside of each bearing. Add a smidge of oil to the inside of each bearing too, before reassembling the motor.

Make sure the motor screws are as tight as possible, and then with a screwdriver handle or similar instrument, give the motor shaft a few taps on one side, then a few on the other (this will align the bearings correctly.
Before reattaching the motor, on the other side of the fan unit you will see a little round metal or plastic cover held in place by a rubber gromit. This is the access to the spindle bearing. Pop this cover off and replace the grease under it, add a bit of machine oil too if you like (it cant hurt) and then replace the cover.

Reassemble everything again, and test.

The heater operation is very noisy compared to new. Perhaps it's the fan? The heater is six years old and I'm concerned that it may cause a fire.

Its most likely the bearings in the fan motor failing causing vibration. One simple way would be too check and make sure all nuts and screws and bolts are tight around th e fan. If so is the fan blade dirty it doesnt take much dirt on a fan blade to get it out of balance and cause bearing failure.

Bad motor bearing?

If you know how (and have the tools;PULLER,nut drivers,slotted and phillips screw driver,hammer,deep socket set,dikes,vise,work bench,and some high temp bearring grease) to take things appart in general, you should be able to disassemble the fan motor and either pull bearings off shaft and replace or repack w/high temp grease if not sealed bearrings. If cannot aquire a puller for removal then attempt to blow all dirt/dust off bearring and try thumbing some motor oil (or vegetable oil if no motor oil available) while turning bearing on shaft back and forth till bearrings free up.Then reassemble electric fan motor reverse disassembly(be sure to keep parts staged as they come off for reassembly in area off the work area) "NOT" over oiling the bearrings into electrical/copper areas.

If your dishwasher seems noisy, check these:

Water-inlet valve
Heater fan
Water-inlet valve An aging water-inlet valve can sometimes fail slowly, rather than all at once. It can shudder on and off rapidly, causing the incoming water lines to shake, rumble, and rattle--sometimes violently. If yours is doing this, replace the inlet valve.

Motor If it's the motor that's noisy, either of these may be the "culprit:"

  • As motor bearings wear out, they can become quite loud when the motor runs. They wear out quickly if they frequently get wet, because the water washes away the motor bearing grease. Bearings can get wet if the spin seal is defective. Then there will also be water leaking onto the floor beneath the dishwasher. Replace the seal if it leaks (read about the main tub seal in the "It leaks" section, later).

  • If, from beneath the dishwasher, you can see a round, plastic disc that's mounted to the top of the motor (a "slinger"), it may have broken free of the motor shaft. If so, it could be rattling around the shaft while the motor is running. If that's the problem, you need to replace the motor.

Heater fan If the heater fan bearings are rusted or worn, they may squeal, or scrape loudly during the drying cycle. If this is the problem, replace the fan motor. Alternatively, the fan blade may be loose. If so, you need to replace it.

Pump Small fruit pits, toothpicks, and fragments of glass sometimes get stuck in the pump. When this happens, open the pump and remove the debris. The pump is usually mounted directly to the motor, then attached to the bottom of the dishwasher.

To get to the pump, you usually need to remove the lower rack, the spray arms, and the spray arm support from the inside of your dishwasher. A dishwasher pump isn't obvious. Look for an impeller--a round, plastic fan blade-type device that spins around and pushes the water toward the drain. When you can see the drain impeller, you should be able to see the clogging debris.
