Resistance on heating elements should be 10.8 or more. if it isn't that high you need a new element.

I have a handy lite2 LJ175N and I keep getting FL4 error code but the hot surface ignitor works if I run power to it from an outlet.

Maybe an open circuit at igniter?
Direct power at igniter, does not make it problem free when installed on the heater.
So many variables...
burned fuse for igniter, bad wire connection, broken wire within sheathing,etc,
all of these will cause a resistance change in ohms. Temperature is read by Heater logics in ohms resistance - both set temperature and actual temperature. So if resistance is off, heater may not work. Could be cracked igniter, or shorting to ground. When you remove the heater from igniter operation, by bypassing and installing a direct alternate power source, you are removing all self test features and safety aspect of heater.
FL4 usually means bad igniter - replace it.

Pump does not turn on. there is power to the board but nothing lights up

No power supply to "board" possibly 24vac, or an air type of control, so that the air supply pump is not active. Possibly the power supply to the pump and control board has "popped" the
circuit breaker. Check, the circuit breaker. There may also be a GFI Ground Fault Indicator that acts like a circuit breaker but is more sensitive, especially near water. Look at the receptacle that the motor plugs into. GFI has a test button and a reset button.

Amana electric dryer LE8317W2 tripped circuit breaker. Orange wire fried at end by heat element and was off terminal end. Also the purple wire was fried at thermostat end. I cleaned up connections and...

These units are totally repairable and will run for ever. Need to assume that other damage has occurred as a result of the failed shorted terminal connections.

Possible that the circuit breaker is defective caused by the dryer failure.

Assume that one of the components has shorted to the grounded frame of the dryer.

The 11 ohms of the heater is about right.

Confirm that heater element is not shorted to the dryer frame (heater housing)! This condition would have caused the initial wire terminals to fail and now trip the circuit breaker!

Use an ohm meter and check resistance between hot leads on back of dryer. Check resistance between each hot and neutral.

There is a switch located on the motor that connects power to the heater. When the motor is running the centrifugal switch closes. This saftey circuit confirms that the blower is running before heat is turned on. Check that the switch is not damaged from prior terminal short circuit failure, Repair kit is p/n WPL-501218

Timer is the next check. Same thing confirm that no damage to the switch circuits has occured. Last check thermal fuses and thermostars for short to netural.

Hope this helps?

What would cause my savio wm3600 sump pump to repeatedly kick off breaker

1. The sump pump could be causing an over current situation if it is bound up. If this were the case it would probably kick the breaker immediately or very soon after turning on with breaker reset.
2. There could be an over current situation by having a short in the motor. You can check this with a electric meter used on a DEENERGIZED circuit with it in ohms to test resistance. Motors generally have a resistance of 1.3 to 2.3 ohms. Check by placing the two leads on the two wires going directly to the pump. Must be DEENERGIZED or electrically dead or you may destroy the meter. If resistance is near 0.0 ohms then the motor has an internal short.

3. There could be an over current if the motor is shorted to ground. With DEENERGIZED disconnect the neutral (white wire) and check the resistance as described above with one of the leads on the hot (black) and the other on the ground (green). If low resistance like near zero then shorted to ground

4. The electrical cord could be damaged which may indicate like number 2 or 3 above, examine the cord when removing the pump.

5. The breaker could be bad, but not very likely. Could switch out with an identical one and check.

Finally- if #1, clear obstruction; if #2 or #3 replace pump; if #4 replace cord if possible; if #5 swap breaker.

My brand new 1.5 hp, 230/115 v pentair runs for several minutes, gets hot and then shuts off. (not tripping the breaker) ...wiring was already in place on previous 1.5 hp, 230/115 jacuzzi brand pump for...

It is probably only getting 115V from your circuit which will cause it to overheat and trip the overload yet it will not draw high current which would trip the breaker. Can you confirm your line voltage with a meter? If it is suppoed to be a 230V line then look for a bad leg of power, again, checking each leg to ground using a meter.

50amp breaker for spa heater gets hot after about 45 minutes and then trips. does it need replaced?

MUCH more likely that your heating element needs to be replaced. Check all connections for heat damage, due to resistance. If you ever stop water flow, the heater MUST be turned off, or you can kill it. Fortunately, it costs tons less than the breaker.

I have a 240V hot tub and when I turn on the Cutler-Hammer GFCB250 GFI Circuit Breaker, 50A, it trips immediately. I spoke with a tech support guy from the hot tub mfr who says that the heater and pump...

It is very possible breaker is bad. If you have another 50 amp breaker in the box try swapping them and see if it still trips. GFIC breakers are finicky and they do go bad. I would make sure that the heater is not shorted out before replacing the breaker. It shows 15 ohms which is not what you would normally see which is 9-12 ohms. The reading of 15 ohms you got is high but if the manufacture says that is acceptable then we must assume it is. You also need to test for a short before eliminating the element as a possible cause. Test it with your ohm meter set to the highest setting. Measure between one element terminal and the sheath of the element. Any reading indicates a short to ground indicating the element is bad. If you find it is good then a defective GFCI is really about all it can be.

Intermatic t10004 control panel trips the circuit breaker

That circuit breaker is letting you know that you've got a problem in the electrical wiring.... What's next is to turn the power off to BOTH legs of the breaker.
Begin by physically inspecting all the connections in the timer box, and at the breaker and all the way to the pump motor. Make sure all connections are dry, and there's no water in any of the conduits...this will cause a short circuit and trip the breaker. If there's any bare power leg wires touching a grounding point , this can cause the breaker to trip. Lastly check the motor on the pump; on the motor end, there should be a cap you can remove and use a crescent wrench to make sure the motor shaft is moving freely. It could be jammed with debris....this happens around my pool often because I'm surrounded by trees with needles. If the motor cannot turn freely, this will cause the breaker to blow... I'm pretty sure that your timer isn't the issue... Please let me know what you find out.
