Question about Cozy Enclosed Front Console Heater 70,000 btuh Natural Gas

1 Answer

I can't turn my cozy heater on - it has a small button in the back and I checked it out - there's zero ohms across the two wires - shouldn't there be? I am supposed to turn it on by holding down a gas-valve button turned to the "pilot" position while I repeatedly press an "ignitor" button on top. But while I press this gas-valve button, I don't even hear or smell any gas.

AUTO FAN NOT WORKING BUT FAN ON WORKS


Sounds like the thermostat is either defective or has a bad connection. If you are familiar with using a multimeter (volt-ohm-current meter), it would be the device to use to trouble-shoot this problem. MAKE SURE THE HEATER IS UNPLUGGED!!!

With the meter set on Ohms, and the heater set on auto, set the heater to its lowest temperature setting. You want to see no resistance (close to zeor Ohms) when check across the thermostat (the temperature knob mounts on it). If you see high or infinite resistance, the thermostat's open and therefore defective. If the thermostat checks out OK, continue checking with the meter. You should have about zero Ohms between the hot pin on the power plug (the narrower one in N. America) and the heater motor lead. If it's open (high or infinite resistance), keep the one meter lead on the power plug and trace back, checking each connection until you find the defective one. Don't rule out a broken wire, maybe inside the insulation (but unlikely).

How do you check resistance through the heater coil?


To that defrost heater
set the meter to lowest ohms setting
follow wires that connect to heater up to the top of freezer coil
unplug the 2 wires for the defrost heater/or if on huge plug with all wires in unplug that plug
place meter leads on the the 2 wires for the heater
the meter display should be some where between 5-25 ohms of resistiance

if heater is good it will have contunuty with 5-25 ohms,if bad the meter display either wont change or display OL
if heater check good check defrost thermostat pictured below for ZERO ohms resistiance when cold and frost is built up on freezer coil MUST BE COLD to check. It too should have continuty with ZERO ohms resistiance

If both heater nand defrost thermostat check good the defrost control board will be the problem.

This is what the deforst thermostat looks,yours may be slightly different yet very similar and ina similar place(clipped to top of freezer coil usually on right side)oldtech2332_40.jpg

Cozy heater will not fire, replaced powerpile but gas valve will not open Jumped tstat also


pull stat wires off of valve and put a jumper wire across the 2 TH terminals on the valve, if it comes on could be the stat wire run a peice of stat wire from unit to stat to test.

Hot water does not last long. Model 82vh40-2 mnf. 05/2005


If the lower heating element burns out the upper element will heat the top part of the tank then shutoff. homw depot/lowes etc should carry elements. 1 turn off breaker, remove element access cover (the 2 panels on the front of the heater) test for electricity at the reset button ( uppermost device in upper panel) to make sure power is off. 2 turn off water (I usually turn off the cold water main to stop water cross feeding into hot supply line back into heater) 3 disconnect the 2 wires on the lower element, test with continuity tester. shhould be no continuity between terminals and tank, but around 10 ohms between the 2 terminals. Check the thermostat for continuity if tank is cold thermostat should be closed ie zero ohms across the 2 terminals.
If stat is bad replace stat; disconnect wires push it up out of the spring clip insert new stat reconnect. If element is bad: drain tank. connect garden hose to tank drain valve, open tank drain valve turn water main on to clear rust sediment and get water flowing. Next remove filter screen from a hot water faucet then turn on ( a hot faucet upstairs or higher than tank drain). Now turn water main off, air will now go in through hot faucet and tank will drain, takes about an hour. Use a water heater element wrench about$10 to remove element(s) make sure no bits of rubber gasket are left in element opening- dig em out with a screwdriver if needed. Insert new element with its gasket and tighten. reconnect wires DO NOT TURN ON ELECTRICITY! BE SURE TO FILL WATER HEATER WITH WATER ! Turn water main back on -air will come out of the hot faucet for several minutes. When water runs without any air sputtering, turn off faucet and replace the faucet filter screen. check element(s) for leaks. turn breaker back on.

Kenmore electric dryer model number 86860100 dryer not heating.....cleaned out vents not the problem....everything else seems to work.. I had seen in the past it glow in back of the dryer so I turned out...


hello there:
Testing with an ohm meter checking on a dryer....
These are the places that pass voltage to the heater elements on an electric dryer. In order to check a dryer for no heat, here is a list of places to check. Remember to always unplug the appliance before starting testing with an ohm meter. Always remove wires from the part you are testing with an ohm meter ( write down what goes where first before removing any wires ).
Meter testing and usage tips.
1. Power supply-check power supply at terminal block where cord enters the dryer. Should read 240V. If you read 240V here, tested with a volt meter, unplug dryer and test components with ohm meter.
2. Thermostats-Cycle and safety thermostats-read them with an ohm meter. Should show continuity . How common thermostats work.
3.Timer-The timer has a set of contacts that pass voltage to the heaters. If you can not determine by wiring picture what they are, check across the two terminals with the largest wires on them. The heater wires are almost twice as large as the others. You should read continuity with timer in heat mode.
4. Thermal fuses-In recent years the makers of dryers are using thermal fuses to let you know something is wrong with your dryer. They are generally non resetting and have to be replaced. The thermal fuses are located on the heater element housing and should read continuity if read with an ohm meter. Most blown thermal fuses are the result of vent/air flow problems or a grounded heating element.
5. Selector Switches-Read the wiring picture and determine which switch is closed. You should read continuity across closed switches.
6. Safety Switch on Motor-There is a safety switch on motor to insure that heaters can not come on unless motor is running. It is normally open when the motor is idle/not running, and closes when motor runs. In order to check with an ohm meter, remove the two large wires on motor switch and make them electrically safe. Tape them. Plug the dryer in and start motor. Check continuity across the terminals on the motor switch you removed the heavy wires from. If it is ok you should read continuity. Remember that the smaller wires in a dryer carry the 120V and the large wires carry 240V. There is no voltage on these two terminals with wires removed. It is ok to test with ohm meter.
7. Heat elements-Test heater element with an ohm meter. You will read continuity across a good element 8-12 OHMS

My cozy heater was hit when another appliance fell on it and impacted it. Apparently some safety mechanism shut it off now I can't turn it back on. Thanx


Most heaters have safety switches on them in case they turn over. Ohm the wires and make sure the switch is closed. Most of them are inside and on the side of the heaters. They have 2 wires on them.

Cozy wall heater does not turn on


Hi, I will walk you through to check the stat. Pull off the cover 1st. You will need a screwdriver, a small one. Could be slotted or phillips. Loosen all of the screws you can see until the t-stat comes off. You have 3 sections counting cover. You will now see the sub-base and wires. You should have only 2 wires to the stat. You will need a piece of scrap insulated wire, even a piece of old speaker wire twisted togeter at each end will work. No worry of shock. Just jump or touch across the 2 terminals and hold them on and if it fires up and comes on, the thermostat is the fault. More then likely that will be the problem. Any hardware store will have one. Get a heat milivolt only, even if the salesman trys to sale you a heat/cool 24 volt stat which will work, but will cause problems in the future. I am sure it is stat. If not, contact me and I will walk you through what else would cause this. If the pilot is on, there is no ignitor on this furnace, either a thermopile generator or a thermocouple, a high limit switch and the main gas valve. Keep me posted, it will only take you a few minutes to test the t-stat. Let me know.

The heater will not ignite properly


How old is the thermostat? Also there a limit switches at different points on that unit. If you have a volt ohm meter find the round disc like safety's and ohm them out. Take the wires off the disc before testing them. You should have a continuity should be closed they only open if unit gets too hot. Say something like 180 degree's.

A fast way to check out the thermostat is take a small diameter wire take the cover off the t-stat and jump across the R and the W on the t-stat. If the furnace comes on then t-stat bad. Let me know if this is helpfull. Ken

Cozy one sided wall furnace (no blower motor)


This is a weird one, but make sure all the wire connections are in the correct place. I accidentally miss wired a heater like this and it did the same thing.
